Influence of the synthetic jet on the flow around the hump
V. Skála, M. Matějka
pages 1183 - 1187, full text

The work deals with measurement of characteristics of the synthetic jet generator. Synthetic jet mean velocity in dependence of the parameters of actuating signal (type of signal, frequency, electrical current value) and the velocity profile in the wake behind the hump with controlled boundary layer was studied. A hot wire anemometry method(HWA) measurement technique was used. Profiles of the mean velocity and turbulence intensity behind hump was evaluated. Variants with and without the synthetic jet were measured and compared.
