In this study,a zonal grid refinement method based on the solution of weakly compressible flow equations with large eddy simulation in the finite volume method（FVM） and dynamic subgrid-scale model framework was used to simulate the turbulence structures of a plane-wall flow with Reynolds number Re=U0δ /ν =10 000.Comparison and analysis were conducted on the distributions of time-averaged velocity and velocity fluctuations,as well as on the actual near-wall structures,to verify the accuracy of the turbulence features that were simulated using the zonal grid refinement method.The results show that the zonal embedded grid is a very efficient way to illustrate the turbulence structures of the near-wall region.The present method is easy to implement and extend to small Mach number flow modeling on a collocated irregular FVM mesh system.
