Popis:	Large eddy simulation of turbulent channel flow is carried out at Re τ values of 150 and 395. Mesh refinement effects are evaluated on conventional meshes, then local mesh refinement in streamwise direction is applied and investigated. The goal of the paper is to give proposal about the ideal position of the merging face and to show how many cells can be saved in this case without losing too much accuracy at both Reynolds numbers. The results are compared to DNS data.
