Simulation of the outflow of steam from a high-pressure volume into a closed external region

Abstract

Abstract A numerical simulation of the process of unsteady outflow of steam (steam-water mixture) from a volume under high pressure into a closed region with rigid boundaries is carried out. The calculations used a thermodynamically equilibrium homogeneous model of a vapor-liquid medium. At small and large (up to 0.15 s) times, spatial distributions of pressure, mass vapor content, density and temperature were obtained and analyzed.
