Hydrodynamics of Intensive Self-Exited Oscillations of the Reversed Vane in a Plane Diffuser
The problem of the nonstationary flow of a viscous incompressible fluid in a flat diffuser containing a hinged partition in the form of a reverse vane directed toward the flow is considered. The mechanism of excitation and maintenance of the angular auto-oscillation regime of the vane is revealed, accompanied by shock interaction of the vane sock with the channel walls and the formation of two antiphase pulsating jets at the exit from the diffuser. This mode is reproduced in a physical experiment and in numerical simulation.
