A THERMODYNAMICALLY CONSISTENT RATE-DEPENDENT MODEL FOR TURBULENCE .2. COMPUTATIONAL RESULTS

The governing equations of the thermodynamically consistent rate-dependent turbulence model developed in Part I are briefly reviewed. The requirements of the model are incorporated in a computer code (STARPIC-RATE). The computational model is used to simulate the mean turbulent flow fields behind a plane backward facing step, in a turbulent channel flow, and axisymmetric swirling and non-swirling flows through a pipe with sudden expansion. The results are compared with the available experimental data and the earlier simulations. The model predictions for the channel flow are also compared with those of a recent direct simulation of turbulence.
