CALCULATION AND EXPERIMENTAL INVESTIGATIONS OF THE VENTURI TUBE AS A HYDRODYNAMIC OSCILLATOR

A mathematical model of an unsteady turbulent cavitation liquid fl ow in a Venturi tube with pressure self-oscillations has been constructed on the basis of the system of continuity and Navier-Stokes equations, the k–ε model of turbulence, and a complete cavitation model. The amplitude–frequency characteristics of the pressure oscillations in a Venturi tube, calculated and obtained experimentally, were compared.
