Abstract
A comparison of two differential Reynolds-stress models for aeronautical flows is presented. The ω model herein combines the Speziale–Sarkar–Gatski pressure–strain model with the Launder–Reece–Rodi model toward the wall, where the length scale is supplied by Menter’s baselineωequation. The εh model from Jakirlić and Hanjalić 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 axial vortices.
