A Hybrid LES/RANS Approach Using Anisotropy-Resolving Algebraic Turbulence Models for Predicting Turbulent Heat Transfer

An investigation of LES and Hybrid LES/RANS models for predicting 3-D diffuser flow

“…To investigate the basic model performance, this model was applied to several test cases, including a periodic hill flow with 2-D separation (Abe and Miyata, 2006) and a basic wall-shear flow with turbulent heat transfer (Inuzuka and Abe, 2007), coupled with an advanced higher-order algebraic heat-flux model (Abe and Suga, 2001). The HLR model generally performed well in these test cases, from which it was found that the introduction of an anisotropyresolving NLEVM was effective in improving the accuracy of the total (resolved + modeled) Reynolds stresses not only in general attached wall-shear flows but also in two-dimensional separated near-wall regions.…”
