摘要

GAO-YONG rational turbulence model utilizes no empirical coefficients. The CFD 3d calculation program is developed with the joint application of the model and the OpenFOAM. Two calculation samples are simulated using the program. First, the simulations of backward step flow in different conditions are used to testify the accuracy of GAO-YONG model simulations as for the separation and reattachment flow. And then, GAO-YONG model and Spalart-Allmaras turbulence model are used to simulate an inter-cooled duct. To forecast the separation flow in the inter-cooled duct the results demonstrate that, the higher accuracy of the GAO-YONG model compared with the Spalart-Allmaras model which is not able to predict the separation in the duct.
