Synthetic jet
WebA synthetic jet is an active flow control device that consists of a diaphragm located at the bottom of a small cavity and an orifice in the opposite face that leads to the main flow passage. The diaphragm is forced to oscillate at a prescribed frequency, causing pressure oscillations within the cavity. During the upward stroke, directed fluid ... WebSynthetic fuel can be produced from FT synthesis, a technology invented by Franz Fischer and Hans Tropsch during 1920s and adopted during World War II in Germany. FT synthesis generates straight-chain hydrocarbons which can be further processed into diesel via hydrocracking reaction.

The device which produces this jet consists of a cavity with rigid side walls, an oscillating diaphragm and a rigid cap with an orifice. Fig. 1 shows the basic synthetic jet concept.
Web“Synthetic” jet flows are similar to pulsed jets in that they are also produced by the advection and interactions of trains of discrete vortical structures. However, a unique feature of synthetic jets is that they are formed entirely from the working fluid of the flow system in which they are deployed and, thus, can transfer linear http://aero-comlab.stanford.edu/Papers/6262776.pdf
