The problem of modeling the process of air blowing through finely perforated wall for skin friction reduction

Reporter: Kornilov V.I.

Problems of experimental modeling of the process of air blowing into turbulent boundary layer of incompressible
fluid through finely perforated wall are discussed. Particular attention is paid to the analysis of both the main factors responsible for the effectiveness of blowing and the possibility of studying the factors in artificially generated turbulent boundary layer. It was shown that uniformity of the injected gas is one of the main requirements to enhance
the effectiveness of this method of flow control. Numerous examples of the successful application of this
technology exhibiting a significant reduction of the turbulent skin friction are provided.
