The effects of controls of turbulent boundary layers on the porous convex curvature surfaces with suction or injection are analyzed by experiments and numerical calculations. In the experiments, velocity profiles and some turbulent characteristic profiles are measured for respective conditions of assorted items of three kinds of convex curvature and three varieties of suction and injection. Then, for the corresponding experimental conditions, the development of turbulent boundary layers is estimated by numerical calculations as compared with the experimental data. The accuracy of estimated values by use of two types of Reynolds stress models by Launder, Reece and Rodi; i. e., high and low Reynolds number types, are compared and evaluated. Finally, the effects of the pile up of conditions; i. e., convex curvatures, suction or injection and adverse pressure gradients are calculated numerically, and some effects of involved conditions are clarified.
