Gurney flap effect using jet induced by plasma actuator

Nihon Kikai Gakkai ronbunshu, 2015
Lift and drag variations by plasma actuators have been investigated under flow at low Reynolds numbers ranging from 1.7×104 to 6.6×104. Wall-normal-jet type and counter-jet type plasma actuators are attached on the pressure surface near the trailing edge
