Skewness depends on shape of mesh. Keeping it to 0 is identical. Aspect ratio is ratio of width & height of the cell. Keeping it 1 is identical. Thanks, WebThe wakes of wall-mounted small (square) and large (long) depth-ratio rectangular prisms are numerically studied at Reynolds numbers of 50–250. The large depth-ratio significantly alters the dominance of lateral secondary flow (upwash and downwash) in the wake due to the reattachment of leading-edge separated flow on the surfaces of the prism.
