Numerical investigation of mixing layer flow using a modified Gao-Yong turbulence model

The mixing layer, one kind of free stream flow was simulated using a modified Gao-Yong turbulence model based on the unilateral statistical average method. The numerical method used in this simulation is an unstructured staggered mesh scheme. The computational results show that the modified Gao-Yong turbulence model can successfully simulate self-preserving characteristics. Both scaled mean velocity profiles at different locations for the mixing layer and scaled mean velocity profiles in the self-preserving region for the mixing layer are in agreement with experiments.
