N2 - To overcome the limitation of LES (large eddy simulation) for wall problem, in recent years, LES/RANS hybrid method became popular, which not only combined the advantages of LES and RANS but also avoided the disadvantage of them. Base on the relationship of value of velocity stress stain S and vorticity Ω, we proposed a new hybrid method to overcome the default of original hybrid method. Whether the LES region or the RANS region was active dynamically depends on the value S/Ω.The results accorded well with experiment. The reliability was checked to make sure that RANS computation region was active properly.
