Abstract: [eng] [cze]
The paper deals with influence of the passive and active method of control on the flow field. It is well known fact that boundary layer separation has a fundamental effect on aircraft airfoil performance, compressors and turbines performance and other bodies, subject to study of internal and external aerodynamics. By the boundary layer control, it is possible to obtain both operational economy and extension of efficient operational region. Traditional methods of active boundary layer control are very complex and their application needs complex facilities. Modern methods based on the control by synthetic jets or plasma actuator 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. Článek se věnuje vlivu pasivních a aktivních metod řízení na proudové pole. Odtržení proudění má zásadní vliv na výkonost leteckcýh profilů, kompresorů, turbin a dalších technických zařízení. Řízením mezní vrstvy je možné dosáhnout významné redukce rozsahu odtržení.
