Calculation and Experimental Investigations of the Venturi Tube as a Hydrodynamic Oscillator
Abstract
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-ɛ 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.
