Аннотация: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. The mathematical problem of the interaction of a reverse vane with the flow of a viscous fluid in a diffuser is solved in a complete coupled formulation in which a continuous medium and a moving solid are described as a single dynamical system without splitting into dynamic and hydrodynamic components. The calculations were performed with the help of the author’s program code based on the gridless numerical VVD method for solving two-dimensional Navier-Stokes equations.
