Development of a diverter piloted switched vortex valve for secondary flow modulation

Abstract:

Active modulation of coolant flow rates would improve cycle efficiencies for jet engines. This thesis presents a proof of concept multistage fluidic device, the staged switched vortex valve (staged SVV), which modulates flow rates by switching between high and low flow impedance states. It is shown that the device can be actively switched between states using conventional mass flow injection and, with minimal modifications, 200 Hz acoustic tones.

A grey-box model of the staged sw...
