abstract = {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=10000. 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.}
