A synthetic jet can be produced over broad range of time and length-scales. Theirs unique attributes make them attractive fluidic actuators for various flow-control tasks. Generation, evolution and interaction of synthetic jets are reviewed in the presented paper. Application of this actuator type ranging from separation and turbulence control, control to thrust vectoring and mixing augmentation to skin friction control is shown. and Obsahuje seznam literatury
The article deals with the influence of phase modulated synthetic jet on the aerodynamics of the hump in a closed test section of the Eiffel-type wind tunnel. Three experimental methods of measurement techniques of this phenomenon, were used: the pressure profile using the Kiel total pressure probe, the velocity profile using the CTA probe and the visualization of the flow field using the hot film and the thermo camera. The experimental results with and without the influence of the synthetic jet were compared, as well the impact of the phase shift of the neighbouring synthetic jets. As a reference case, the flow around the hump without the influence of the syntheic jet was selected. The results of the measurement are presented in figures and compared. and Obsahuje seznam literatury
