Abstract
A new phenomenological turbulence transition model is proposed. The model is based on the calculation of the pre-transitional u′v′‾ due to mean flow shear. This is used for analysis on the complex flow patterns over three-dimensional geometries. The tested 3D cases are the 6:1 prolate-spheroid under three flow conditions and the transonic DLR-F5 wing test case. The obtained results are compared with the low-Reynolds turbulence model of Spalart–Allmaras and the empirical transition model, γ-Reθγ-Reθ. These show that the developed transition model is able to capture the flow turbulence transition features experimentally recorded.
