    Abstract
  • A preconditioned dual-time stepping method is developed for the multi-component flow regimes including the incompressible bulk liquid flow, low Mach number compressible vapor flow and transonic/supersonic mixture flow with cavitations. The governing equations involving liquid-gas phase change and/or gas phase chemical reaction as source terms are discretized with a multi-block structured grid via upwind flux difference scheme with flux limits(Roe-type). Several representative solutions are obtained to demonstrate the feasibility of the presented method.
