Abstract

The dynamics of thermal processes in non-equilibrium wet-steam flows has been analysed on the basis of a general model of multiphase media behaviour. The governing dynamic equations have been derived and a method of determining additional exergy losses due to non-equilibrium efects, based on an introduced concept of predicted entropy increments has been suggested. An analysis of flow choking and methods of defining the critical parameters have been presented. Two computational methods have been developed and calculations of non-equilibriun flows around a profile have been carried out.
