Abstract
An open-source solver for the subsonic flow around an airfoil is developed and validated. It couples potential and boundary layer theory and is designed for allowing the imposition of wall-normal blowing or suction at desired positions along the airfoil. The solver is used for assessing the capability of uniform blowing (UB) to reduce overall drag of airfoils, for which not only friction but also pressure drag is present. It is shown that the physical description offered by the combined potential and boundary layer theory is sufficient to model the effect of uniform blowing on the airfoil performance at least at a qualitative level.
