A comparison of two differential Reynolds stress models for aeronautical flows is presented. The SSG/LRR-omega model combines the Speziale-Sarkar-Gatski (SSG) pressure-strain model with the Launder-Reece-Rodi (LRR) model towards the wall, where the length scale is supplied by Menter’s BSL omega-equation. The JHh-v2 model from Jakirlic and Hanjalic has been particularly designed for representing the correct near wall behavior of turbulence and has been adapted to aeronautical needs. Its length scale is provided by a transport equation for the homogeneous part of the dissipation rate. The models are applied to a series of test cases relevant to aeronautics, showing improved predictions compared to eddy viscosity models particularly in case of separation.
