Entropy generation rates in helium boundary layer flows for five cases of increasing temperature and pressure are considered. The basic format of a turbulent spot is used as the flow model. Statistical processing of the time-dependent series solutions of the nonlinear, coupled Lorenz-type differential equations for the spectral velocity wave components in the three-dimensional boundary layer configuration yields the local volumetric entropy generation rates. Extension of the computational method to the transition from laminar to fully turbulent flow is discussed.<\/jats:p>","DOI":"10.3390\/e19060278","type":"journal-article","created":{"date-parts":[[2017,6,15]],"date-time":"2017-06-15T10:07:33Z","timestamp":1497521253000},"page":"278","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Entropy Generation Rates through the Dissipation of Ordered Regions in Helium Boundary-Layer Flows"],"prefix":"10.3390","volume":"19","author":[{"given":"LaVar","family":"Isaacson","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, University of Utah, Salt Lake City, UT 84112, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,6,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Isaacson, L.K.
