Active flow control on the simplified flapped airfoil

Original language description

The paper deals with control and influence of synthetic jets to the flow field at conditions near boundary layer separation. Traditional methods of boundary layer control are very complex and their application needs complex facilities. Modern methods based on the control by synthetic jets are simpler, but their design has to be carried out at rather well experience and detailed knowledge about boundary layer and its interaction with the actuator. Two types of synthetic jets were used on two test cases on simplified airfoil with flap. First measured task was focused on laminar separation bubble suppression, the other on delay of turbulent separation on the flap. The influence of jet output geometry was studied on a row of orifices and a slot. Variationof control frequencies was performed.
