review text: A B-spline based numerical method on a zonal embedded grid has been developed. The method is aimed at reducing the computational requirements for large eddy simulations (LES) and direct numerical simulations (DNS) of wall-bounded turbulent flows. The objective is to reduce the number of grid points required to resolve the near-wall eddies without placing a large number of grid points in the outer layers. DNS and LES calculations of a turbulent channel flow were performed on a grid with a zone near the wall that was refined in all three directions. The results from the zonal grid calculations show good agreement with previously published numerical and experimental results.
