Abstract
A compressible bubble-liquid mixture flow model is developed for computing high-speed cavitation flows by coupling a bubble dynamic calculation based on the Two-Fluids Three-Pressure model and a compressible mixture flow procedure. General Navier-Stokes equations for compressible fluid are employed to simulate the flow of two-phase mixture. State equations of liquid and gas phases are adopted and a relation for the mixture density and pressure is derived. As an example, cavitating and no-cavitating flows in a Venturi nozzle are treated and the capability of present model is demonstrated.
