Title: Study on Detached Eddy Simulation Method and its Application
Abstract: Based on the in-housed methods of unsteady Reynolds average N-S equations,detached eddy simulation(DES) is developed in this paper.Solver of RANS with S-A turbulence model is used in the turbulent boundary layer,while,in the other domains of flow fields,Smagorinski′s LES model combining with S-A model is implemented,which makes the improved model be used as S-A model and Smagorinski large eddy simulation model.To verify the effectiveness of the method developed,DES in this study is applied to some typical flow field calculations and some comparisons are also made by the references′ results and experimental results.
