Numerical Modeling of Two - Phase Transonic Flow
Original language description
Our work is aimed at the development of numerical method for the modeling of transonic flow of wet steam including condensation/evaporation phase change. We solve a system of PDE's consisting of Euler or Navier-Stokes equations for the mixture of vaporand liquid droplets and transport equations for the integral parameters describing the droplet size spectra. Numerical method is based on a fractional step technique due to the stiff character of~source terms, i.e. we solve separately the set of homogenous PDE's by the finite volume method and the remaining set of ODE's either by explicit Runge-Kutta or implicit Euler method. The finite volume method is based on the Lax-Wendroff scheme with conservative artificial dissipation terms for structured grid. We discuss numerical results of steady and unsteady two-phase transonic flow in 2D nozzle, 2D and 3D turbine cascade and 2D turbine stage with moving rotor cascade.
