... in the levels of turbulence and unsteady intensities, mainly in the diffuser channels. (iii) Similar levels of turbulence and unsteady intensities were noted for different impeller speeds but the same flow coefficient, showing that the rules of similarity can be applied to such variables.

... as similarity results. The distance where the similarity profile forms is reduced by increasing the step geometry whereas an increment in Re increases this distance. The effects of Re, step length, and step height on wall vorticity are presented. The parametric study is helpful to predict the reattachment...
