It is, perhaps, the most important variable used to characterize a burning fuel packet and is defined as the rate of energy released by the fire. HRR is typically determined using a gas measurement calorimetry method. In this study, an inversion algorithm is presented for conducting calorimeter on fires with unknown HRRs located in a compartment. The algorithm compares predictions of a forward model with observed heat fluxes from synthetically generated data sets to determine the HRR that minimizes a cost function. The effects of tuning a weighting parameter in the cost function and the issues associated with two different forward models of a compartment fire are examined.<\/jats:p>","DOI":"10.1115\/ht2017-5107","type":"proceedings-article","created":{"date-parts":[[2017,10,19]],"date-time":"2017-10-19T19:35:54Z","timestamp":1508441754000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":1,"title":["Inversion for Fire Heat Release Rate Using Transient Heat Flux Data"],"prefix":"10.1115","author":[{"given":"Andrew","family":"Kurzawski","sequence":"first","affiliation":[{"name":"University of Texas at Austin, Austin, TX"}]},{"given":"Ofodike A.","family":"Ezekoye","sequence":"additional","affiliation":[{"name":"University of Texas at Austin, Austin, TX"}]}],"member":"33","published-online":{"date-parts":[[2017,10,18]]},"event":{"sponsor":["Heat Transfer Division"],"acronym":"HT2017","name":"ASME 2017 Heat Transfer Summer Conference","start":{"date-parts":[[2017,7,9]]},"location":"Bellevue, Washington, USA","end":{"date-parts":[[2017,7,12]]}},"container-title":["Volume 1: Aerospace Heat Transfer; Computational Heat Transfer; Education; Environmental Heat Transfer; Fire and Combustion Systems; Gas Turbine Heat Transfer; Heat Transfer in Electronic Equipment; Heat Transfer in Energy Systems"],"link":[{"URL":"http:\/\/asmedigitalcollection.asme.org\/HT\/proceedings-pdf\/doi\/10.1115\/HT2017-5107\/2442036\/v001t05a003-ht2017-5107.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,2]],"date-time":"2019-09-02T08:42:41Z","timestamp":1567413761000},"score":10.1143,"resource":{"primary":{"URL":"https:\/\/asmedigitalcollection.asme.org\/HT\/proceedings\/HT2017\/57885\/Bellevue,%20Washington,%20USA\/289303"}},"issued":{"date-parts":[[2017,7,9]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1115\/ht2017-5107","published":{"date-parts":[[2017,7,9]]},"article-number":"V001T05A003"},{"indexed":{"date-parts":[[2025,7,30]],"date-time":"2025-07-30T13:03:28Z","timestamp":1753880608332,"version":"3.41.2"},"reference-count":0,"publisher":"American Society of Mechanical Engineers","content-domain":{"domain":["asmedigitalcollection.asme.org"],"crossmark-restriction":true},"published-print":{"date-parts":[[2016,7,10]]},"abstract":"<jats:p>Thermal energy storage (TES) systems using phase change materials (PCMs) are used in various engineering applications.

We report an experimental study which was conducted to investigate the melting process and associated heat transfer in a rectangular chamber with a cylindrical u-shaped heat source imbedded inside the PCM. The results showed that geometry and orientation of the heat source immensely influenced the heat transfer behavior during solid-liquid phase transition. The heat transfer behavior, interface movement and the heat transfer coefficients differed both axially and vertically inside the chamber as well as with the melting rate. The local convective heat transfer coefficient, hlocal in the inner region, enclosed by the U-tube, was observed to increase at a higher rate than the outer region. Stronger convective flow and a lower viscosity owing to higher temperature in the inner region is believed to have caused faster melting in this region. The melting rate was also found comparatively higher until approximately two-third of the PCM volume was melted before the rate declined.<\/jats:p>","DOI":"10.1115\/ht2016-7232","type":"proceedings-article","created":{"date-parts":[[2016,11,11]],"date-time":"2016-11-11T14:39:52Z","timestamp":1478875192000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":0,"title":["Effect of Heat Source Geometry on the Transient Heat Transfer During Melting Process of a PCM"],"prefix":"10.1115","author":[{"given":"Mohammad","family":"Bashar","sequence":"first","affiliation":[{"name":"University of Western Ontario, London, ON, Canada"}]},{"given":"Kamran","family":"Siddiqui","sequence":"additional","affiliation":[{"name":"University of Western Ontario, London, ON, Canada"}]}],"member":"33","published-online":{"date-parts":[[2016,11,11]]},"event":{"name":"ASME 2016 Heat Transfer Summer Conference collocated with the ASME 2016 Fluids Engineering Division Summer Meeting and the ASME 2016 14th International Conference on Nanochannels, Microchannels, and Minichannels","start":{"date-parts":[[2016,7,10]]},"sponsor":["Heat Transfer Division"],"location":"Washington, DC, USA","end":{"date-parts":[[2016,7,14]]},"acronym":"HT2016"},"container-title":["Volume 2: Heat Transfer in Multiphase Systems; Gas Turbine Heat Transfer; Manufacturing and Materials Processing; Heat Transfer in Electronic Equipment; Heat and Mass Transfer in Biotechnology; Heat Transfer Under Extreme Conditions; Computational Heat Transfer; Heat Transfer Visualization Gallery; General Papers on Heat Transfer; Multiphase Flow and Heat Transfer; Transport Phenomena in Manufacturing and Materials Processing"],"link":[{"URL":"http:\/\/asmedigitalcollection.asme.org\/HT\/proceedings-pdf\/doi\/10.1115\/HT2016-7232\/2441984\/v002t08a014-ht2016-7232.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,1]],"date-time":"2019-09-01T08:25:14Z","timestamp":1567326314000},"score":10.069195,"resource":{"primary":{"URL":"https:\/\/asmedigitalcollection.asme.org\/HT\/proceedings\/HT2016\/50336\/Washington,%20DC,%20USA\/243566"}},"issued":{"date-parts":[[2016,7,10]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1115\/ht2016-7232","published":{"date-parts":[[2016,7,10]]},"article-number":"V002T08A014"},{"indexed":{"date-parts":[[2025,7,30]],"date-time":"2025-07-30T12:53:13Z","timestamp":1753879993934,"version":"3.41.2"},"reference-count":0,"publisher":"American Society of Mechanical Engineers","content-domain":{"domain":["asmedigitalcollection.asme.org"],"crossmark-restriction":true},"published-print":{"date-parts":[[2017,7,9]]},"abstract":"<jats:p>Most thermal engineers will model and analyze thermal engineering cases, using any of the numerous thermal analysis software, available in the market.

In particular, the effect of bosses, used for mounting components, on the fluid flow distribution and temperature distribution in the heat sink are evaluated. A typical heat sink has fins sandwiched between top and bottom plates, with electronic components mounted on the plates. The top and bottom plates spread the heat generated in the components to reduce the local heat flux. The fins substantially increase the heat transfer area, reducing the temperature rise from the coolant to the top and bottom plates. In this case a uniform distribution of flow across the heat sink can be achieved and there will be no localized hot spots. Ideally there are no protrusions into the finned portion of the heat sink which would cause disruptions in the uniform flow through the heat sink. However, a boss may be needed to bolt a component to the heat sink. The presence of the boss has three effects on the heat sink performance. The boss disrupts the flow in its immediate vicinity, increasing the thermal resistance. This will cause an increase in operating temperature at that location. In addition, the boss will change the flow distribution in the heat sink. Locations upstream and downstream of the boss may see reduced flow due to the obstruction, which in turn will cause an increase in operating temperature for these areas of the heat sink. Finally, the change in flow distribution may increase the pressure drop through the entire heat sink, increasing the power required to operate the system. The purpose of this study is to numerically evaluate the clearance requirements around circular bosses. Comparisons between an unobstructed heat sink and a heat sink with an obstruction are made for the maximum component temperature rise, the pressure drop and the flow distribution. Clearance ratios, diameter of the fin cut out to boss diameter, were varied from 1.1 to 3.3. The Reynolds number for the flow was varied from roughly 3000 to 70,000 based on the hydraulic diameter of flow passage.<\/jats:p>","DOI":"10.1115\/ht2017-4715","type":"proceedings-article","created":{"date-parts":[[2017,10,19]],"date-time":"2017-10-19T19:35:54Z","timestamp":1508441754000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":0,"title":["Numerical Evaluation of Clearance Requirements Around Obstructions in Finned Heat Sinks"],"prefix":"10.1115","author":[{"given":"Steven","family":"Miner","sequence":"first","affiliation":[{"name":"United States Naval Academy, Annapolis, MD"}]}],"member":"33","published-online":{"date-parts":[[2017,10,18]]},"event":{"name":"ASME 2017 Heat Transfer Summer Conference","start":{"date-parts":[[2017,7,9]]},"sponsor":["Heat Transfer Division"],"location":"Bellevue, Washington, USA","end":{"date-parts":[[2017,7,12]]},"acronym":"HT2017"},"container-title":["Volume 1: Aerospace Heat Transfer; Computational Heat Transfer; Education; Environmental Heat Transfer; Fire and Combustion Systems; Gas Turbine Heat Transfer; Heat Transfer in Electronic Equipment; Heat Transfer in Energy Systems"],"link":[{"URL":"http:\/\/asmedigitalcollection.asme.org\/HT\/proceedings-pdf\/doi\/10.1115\/HT2017-4715\/2442026\/v001t08a001-ht2017-4715.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,2]],"date-time":"2019-09-02T12:19:30Z","timestamp":1567426770000},"score":10.0378065,"resource":{"primary":{"URL":"https:\/\/asmedigitalcollection.asme.org\/HT\/proceedings\/HT2017\/57885\/Bellevue,%20Washington,%20USA\/289308"}},"issued":{"date-parts":[[2017,7,9]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1115\/ht2017-4715","published":{"date-parts":[[2017,7,9]]},"article-number":"V001T08A001"},{"indexed":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T08:15:32Z","timestamp":1758269732360,"version":"3.41.2"},"reference-count":0,"publisher":"American Society of Mechanical Engineers","content-domain":{"domain":["asmedigitalcollection.asme.org"],"crossmark-restriction":true},"published-print":{"date-parts":[[2016,7,10]]},"abstract":"<jats:p>Numerical results are presented for laminar impinging flow and heat transfer with a non-Newtonian inelastic fluid in a planar two dimensional geometry.

Thermal analysis is performed to investigate a novel wavy-tapered channel configuration of microchannel heat sinks with directionally alternating coolant flow for high-end electronics cooling. Simulations were conducted at different tapering and aspect ratios, focusing on how effectively previously proven geometric enhancements combine with one another in novel ways. Results confirmed the superiority of wavy channels over straight channels due to the development of the secondary flow (Dean Vortices), which enhance the advection mixing and consequently the overall heat sink thermal performance. Moreover, width-tapering of the wavy channel showed improved channel performance in terms of thermal resistance compared to untapered wavy channels. Almost 10% improvement in thermal resistance is obtained with width tapering. Also, the thermal performance showed a strong dependency on channel aspect ratio.

These ethanol nanodroplets can serve as pre-seed boiling nuclei at elevated temperature.

This study investigates the use of liquid\/gas slug flows where a liquid coolant is segregated into discrete slugs, resulting in a segmented flow, and heat transfer rates are enhanced by an internal circulation within slugs. This circulation directs cooler fluid from the center of the slug towards the heated surface and elevates the temperature difference at the wall. An experimental facility is built to examine this problem in circular tube flow with a constant wall heat flux boundary condition. This was attained by Joule heating a thin walled stainless steel tube. Water was used as the coolant and air as the segregating phase. The flow rates of each were controlled using high precision syringe pumps and a slug producing mechanism was introduced for segmenting the flow into slugs of various lengths at any particular flow rate. Tube flows with Reynolds numbers in the range 10 to 1500 were examined ensuring a well ordered segmented flow throughout. Heat transfer performance was calculated by measuring the exterior temperature of the thin tube wall at various locations using an Infrared camera. Nusselt number results are presented for inverse Graetz numbers over four decades, which spans both the thermally developing and developed regions. The results show that Nu in the early thermally developing region are slightly inferior to single phase flows for heat transfer performance but become far superior at higher values of inverse Gr. Additionally, the slug length plays an important role in maximizing Nusselt number in the fully developed region as Nu plateaus at different levels for slugs of differing lengths. Overall, this paper provides a new body of experimental findings relating to segmented flow heat transfer in constant heat flux tubes without boiling.

Parametric studies that varied channel widths showed that as these widths were reduced, and the total number of channels increased, temperature and pressure predictions from both models converged to similar values. Relative differences as low as 5.4 and 1.6 % were attained at a channel width of 0.25 mm for maximum wall temperatures and channel pressure drops, respectively. Based upon its computational efficiency and conservative over prediction of wall temperatures, the unit cell approach is recommended as a superior design tool for parametric design studies at channel widths of less than 0.5 mm.<\/jats:p>","DOI":"10.1115\/ht2016-7076","type":"proceedings-article","created":{"date-parts":[[2016,11,11]],"date-time":"2016-11-11T14:39:52Z","timestamp":1478875192000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":2,"title":["A Comparison of Numerical Strategies for Optimal Liquid Cooled Heat Sink Design"],"prefix":"10.1115","author":[{"given":"Ali C.","family":"Kheirabadi","sequence":"first","affiliation":[{"name":"Dalhousie University, Halifax, NS, Canada"}]},{"given":"Dominic","family":"Groulx","sequence":"additional","affiliation":[{"name":"Dalhousie University, Halifax, NS, Canada"}]}],"member":"33","published-online":{"date-parts":[[2016,11,11]]},"event":{"name":"ASME 2016 Heat Transfer Summer Conference collocated with the ASME 2016 Fluids Engineering Division Summer Meeting and the ASME 2016 14th International Conference on Nanochannels, Microchannels, and Minichannels","start":{"date-parts":[[2016,7,10]]},"sponsor":["Heat Transfer Division"],"location":"Washington, DC, USA","end":{"date-parts":[[2016,7,14]]},"acronym":"HT2016"},"container-title":["Volume 2: Heat Transfer in Multiphase Systems; Gas Turbine Heat Transfer; Manufacturing and Materials Processing; Heat Transfer in Electronic Equipment; Heat and Mass Transfer in Biotechnology; Heat Transfer Under Extreme Conditions; Computational Heat Transfer; Heat Transfer Visualization Gallery; General Papers on Heat Transfer; Multiphase Flow and Heat Transfer; Transport Phenomena in Manufacturing and Materials Processing"],"link":[{"URL":"http:\/\/asmedigitalcollection.asme.org\/HT\/proceedings-pdf\/doi\/10.1115\/HT2016-7076\/2441956\/v002t11a002-ht2016-7076.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,1]],"date-time":"2019-09-01T13:25:18Z","timestamp":1567344318000},"score":9.952181,"resource":{"primary":{"URL":"https:\/\/asmedigitalcollection.asme.org\/HT\/proceedings\/HT2016\/50336\/Washington,%20DC,%20USA\/243504"}},"issued":{"date-parts":[[2016,7,10]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1115\/ht2016-7076","published":{"date-parts":[[2016,7,10]]},"article-number":"V002T11A002"}],"items-per-page":20,"query":{"start-index":0,"search-terms":"Heat"}}}
