摘要：

Numerical simulation of separated flow around a triangular cylinder and turbulent flow over a rearward-facing step in a diverging channel flow using GAO-YONG turbulence model were presented. All calculations were based on open field operation and manipulation (OpenFOAM), which is a open-source computational fluid dynamics (CFD) platform. The calculations predict the vortex shedding of flowing around bluff body and reattachment of flowing over rearward-facing step in a channel accurately. The distribution of pressure coefficient, friction coefficient and velocity were simulated numerically with GAO-YONG model, and agreed well with the experimental data. The results demonstrate that GAO-YONG turbulence model was capable to simulated the turbulent flow with large separation, and be of basic instructional effect to engineering and practice.
