A low-Reynolds-number second-moment closure which completely eliminates wall-reflection redistribution terms is tested in turbulent flows with wall blowing and suction. The turbulence model was previously shown to give good predictions for fully-developed channel flow, boundary layers in adverse and favorable pressure gradients, and plane and round jets. In the present study, the model is used to calculate three boundary layers with blowing, two boundary layers with suction, and a channel flow with blowing and suction. The predictions are generally in good agreement with experimental data or direct numerical simulation data. The result encourages further testing of the model in various turbulent flows to establish a second-moment closure without wall-reflection redistribution terms.
