Abstract : The effect of an asymmetric transition on wall shear stress is presented. It is shown that the Magnus force and moment can be substantially changed due to the shear stress contribution for the mixed boundary layer case on a spinning body. Comparison is made with the Magnus contributions due to pressure forces indicating the shear stress can account for as much as fifty percent or more of the total side force and moment. Some experimental data are analyzed to illustrate the trends predicted. (Author)
