Theoretical and Engineering Aspects of Mass Exchange through a Permeable Streamlined Surface

Abstract

The subject of the study is mass transfer through a permeable surface in the form of blowing and suction, both individually and in various combinations, which is one of the most effective and promising methods for controlling turbulent wall flows. However, the practical feasibility of this delicate technology requires its careful adaptation to the mode of intended functioning, including taking into account the negative impact of real weather conditions. Particular attention is paid to such configurations as the wing section (airfoil) and the body of revolution (fuselage). Based on CFD and experimental techniques, several typical geometric and regime configurations of this method implementation were studied and analysed. The results obtained allow to identify a number of priority directions for improving the efficiency of turbulent boundary layer control in the expected operating conditions.
