Abstract

The analysis of the efficiency of turbulent boundary-layer control on low-speed airfoils using mass transfer through a permeable wall is presented. Particular attention is paid to the consideration of the physical properties of the wall flow in the presence of positive (from the wall) and negative (to the wall) mass transfer and the aero-dynamic characteristics of airfoils under conditions of distributed or localized action of mass transfer of varying intensity on the boundary layer.
