ABSTRACT

The present paper performs Detached-Eddy Simulations of the actively controlled flow over a 0.35 m chord NACA0015 airfoil at an incidence angle of 11° and a chord Reynolds number of 1 million. Flow separation can be delayed by pulsed blowing through a slot positioned at 30% of the chord length. By simulating different excitation frequencies and intensities, an optimum flow control condition is identified, which agrees well with the one in experiment.
