In this work, we investigate the effect of employing a rectangular winglet having a punched hole on heat transfer and flow resistance characteristics in a fin-tube heat exchanger with the help of numerical simulations. Studies were performed on two configurations, namely, common flow down and common flow up at upstream and downstream locations. Performance characteristics such as Colburn\u2019s factor ( j), friction factor ( f), and performance evaluation criterion were considered for evaluating the thermohydraulic performance. Investigations were performed considering Reynolds number in the range of 1500\u20139000, keeping the angle of attack as 45\u00b0. The shear stress transport k-\u03c9 turbulence model was used for performing numerical simulations. A significant augmentation of up to 71% in the thermohydraulic performance of fin-tube heat exchanger was observed with the common flow down configuration located upstream over the common flow up configuration located upstream, which displayed the least improvement. <\/jats:p>","DOI":"10.1177\/1063293x19891770","type":"journal-article","created":{"date-parts":[[2019,12,13]],"date-time":"2019-12-13T06:24:05Z","timestamp":1576218245000},"page":"47-57","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Computer-aided engineering analysis for the performance augmentation of a fin-tube heat exchanger using vortex generator"],"prefix":"10.1177","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1898-5752","authenticated-orcid":false,"given":"Sachin","family":"Gupta","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, YMCA University of Science and Technology, Faridabad, India"},{"name":"Department of Mechanical and Automation Engineering, Maharaja Agrasen Institute of Technology, Delhi, India"}]},{"given":"Aditya","family":"Roy","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Indian Institute of Technology, Delhi, India"}]},{"given":"Arvind","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, YMCA University of Science and Technology, Faridabad, India"}]}],"member":"179","published-online":{"date-parts":[[2019,12,12]]},"reference":[{"key":"bibr1-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/0017-9310(94)90099-X"},{"key":"bibr2-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijheatmasstransfer.2017.11.121"},{"key":"bibr3-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1205\/026387698524686"},{"key":"bibr4-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1615\/IHTC9.1290"},{"key":"bibr5-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/j.applthermaleng.2014.09.043"},{"key":"bibr6-1063293X19891770","volume-title":"Experimental Methods for Engineers","author":"Holman J","year":"2004","edition":"7"},{"key":"bibr7-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/0894-1777(95)00066-U"},{"key":"bibr8-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/j.apenergy.2015.07.065"},{"key":"bibr9-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1115\/1.4041832"},{"key":"bibr10-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.2514\/3.12149"},{"key":"bibr11-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.2514\/3.9974"},{"key":"bibr12-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/j.applthermaleng.2004.10.013"},{"key":"bibr13-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/j.applthermaleng.2005.10.042"},{"key":"bibr14-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/j.icheatmasstransfer.2008.10.018"},{"key":"bibr15-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/S0017-9310(03)00047-4"},{"key":"bibr16-1063293X19891770","volume-title":"Turbulence Modeling for CFD","author":"Wilcox DC","year":"1998","edition":"2"},{"key":"bibr17-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/j.applthermaleng.2015.03.011"},{"key":"bibr18-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1177\/0954408915581995"},{"key":"bibr19-1063293X19891770","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijthermalsci.2013.11.010"}],"container-title":["Concurrent Engineering"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1063293X19891770","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1063293X19891770","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1063293X19891770","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,1]],"date-time":"2025-03-01T23:15:10Z","timestamp":1740870910000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1063293X19891770"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,12,12]]},"references-count":19,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2020,3]]}},"alternative-id":["10.1177\/1063293X19891770"],"URL":"https:\/\/doi.org\/10.1177\/1063293x19891770","relation":{},"ISSN":["1063-293X","1531-2003"],"issn-type":[{"type":"print","value":"1063-293X"},{"type":"electronic","value":"1531-2003"}],"subject":[],"published":{"date-parts":[[2019,12,12]]}}}
