Application of Reynolds-Stress-Models on Free Shear Layers

摘要

This contribution presents the application of the JHh-v2 and JHh-v3 Reynolds-Stress-Model on different test cases with free shear layers. Based on a two-dimensional mixing layer, the need for improvement of the JHh-v2 turbulence model for free shear layers is worked out. An additional sink term within the length-scale equation is implemented and calibrated, resulting in the JHh-v3 model. Simulations of practically relevant test cases with free shear layers are performed using the JHh-v2 and JHh-v3 turbulence models. For comparison, experimental data and results of simulations with the Menter-SST eddy-viscosity model are shown.
