The outcome of an actual LES depends on the quality of the subgrid-scale (SGS) model, as well as the accuracy of the numerical method used to solve the equations for the resolved scales. In this paper, we focus on the influence of SGS models for LES of the diffuser flow through using a high-order finite difference method to solve the equations for the resolved scales. Six resolutions are computed to investigate the influence of mesh resolution. Four existing SGS models, a new one-equation dynamic SGS model and a direct numerical simulation (DNS) are conducted in the diffuser flow. A series of computational analyses is performed to assess the performance of different SGS models on the coarse grids. By comparison with the experiment and DNS, the results produced by the new one-equation dynamic model give better agreement with experiment and DNS than the four other existing SGS models.<\/jats:p>","DOI":"10.3390\/sym11111337","type":"journal-article","created":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T05:18:26Z","timestamp":1572499106000},"page":"1337","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Large-Eddy Simulation of an Asymmetric Plane Diffuser: Comparison of Different Subgrid Scale Models"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5005-3624","authenticated-orcid":false,"given":"Hui","family":"Tang","sequence":"first","affiliation":[{"name":"College of Automotive Engineering, Jilin University, Renmin Street No. 5988, Changchun 130012, China"},{"name":"State Key Laboratory of Automotive Simulation and Control, Jilin University, Renmin Street No. 5988, Changchun 130012, China"},{"name":"Department of Mechanical Engineering, Osaka University, 2-1 Yamada-oka, Suita-city, Osaka 565-0871, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yulong","family":"Lei","sequence":"additional","affiliation":[{"name":"College of Automotive Engineering, Jilin University, Renmin Street No. 5988, Changchun 130012, China"},{"name":"State Key Laboratory of Automotive Simulation and Control, Jilin University, Renmin Street No. 5988, Changchun 130012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingzhong","family":"Li","sequence":"additional","affiliation":[{"name":"College of Automotive Engineering, Jilin University, Renmin Street No. 5988, Changchun 130012, China"},{"name":"State Key Laboratory of Automotive Simulation and Control, Jilin University, Renmin Street No. 5988, Changchun 130012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yao","family":"Fu","sequence":"additional","affiliation":[{"name":"College of Automotive Engineering, Jilin University, Renmin Street No. 5988, Changchun 130012, China"},{"name":"State Key Laboratory of Automotive Simulation and Control, Jilin University, Renmin Street No. 5988, Changchun 130012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,10,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"100","DOI":"10.1016\/j.ijheatfluidflow.2014.04.008","article-title":"Sensitivity of an asymmetric, three-dimensional diffuser to inlet condition perturbations","volume":"49","author":"Sayles","year":"2014","journal-title":"Int.
