THE EFFECT OF TURBULENCE AND REAL GAS MODELS ON THE TWO PHASE SPONTANEOUSLY CONDENSING FLOWS IN NOZZLE

摘要

The aim of the paper is to analyse (ct) of turbulence and real gas models on the process of spontaneous condensation in converging diverging (CD) nozzle by using commercial Computational Fluid Dynamics (CFD) code. The calculations were based on the 2-D compressible Navier-Stokes (NS) equations coupled with two-equation turbulence model, and the non-equilibrium spontaneous condensing steam flow was solved on the basis of the classical nucleation theory. The results were validated to the available experimental data.
