Abstract

An experimental study of a 2D square prism with rounded front edges is described. The purpose of the study is to reduce the aerodynamic drag by Active Flow Control (AFC) of boundary layer separation. Robust and efficient suction and pulsed blowing (SaOB) actuators are installed inside a circular cylinder that forms the upper-front curved edge. In addition and for simplicity, steady suction is applied at the lower-front round edge. The AFC results in significant form-drag reduction, narrower wake and correspondingly an increase in the base pressure.
