Název v původním jazyce

Numerical Solution of Transonic Flow of Condensing Steam

Popis výsledku v původním jazyce

This work deals with a 2D transonic flow of a mixture composed of vapor and liquid phase (droplets). The flow of mixture is modelled by the Euler or Navier-Stokes equations. The whole spectra of droplets is described by the Hill's approximation. The complete set of governing equations consists of the mentioned equation for the mixture and the conservation equations for parameters of Hill's approximation. This set of equations is closed by the equation for the pressure. A particular version of a fractional step method with the different time steps for individual sub-problems is used due to the fast phase changes. The convection-diffusion part is solved by finite volume cell-vertex method based on Lax-Wendroff scheme. A conservative form of common Jameson's artifical viscosity terms is used to stabilize a numerical solution. The condensation part is solved by the two-stage Runge-Kutta method.
