Abstract

The process of hollow jet formation during steam outflow through a thin nozzle was studied; the water steam was initially at high pressure and in the supercritical state. The numerical solution for this problem was obtained with the sonicFoam solver library from the open-source CFD software package OpenFOAM in 2D axisymmetric formula-tion. The reliability of results is estimated by comparing two approaches for simulation of the dynamics of unloading wave propagating in the high-pressure nozzle using the OpenFOAM package with Peng−Robinson equation of state and numerical solution of a similar problem by method of through computation in the case of 1D planar approximation for perfect gas equation of state.
