... of Fig. 15 match virtually well comparing the different rotor speeds, so that similarity is also fairly acceptable for these properties. Inasmuch as these properties should be very sensitive to numerical errors, turbulence model and other effects not considered in the current modeling, such as leakages...

... 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...
