Abstract: 

This paper describes a theoretical study of the self-condensation of non-equilibrium wet steam during supersonic expansion in the Laval nozzle. The nucleation theory and exact droplet growth equations have been combined with equations of one-dimensional gas dynamics and the system integrated numerically on a computer. It has been shown that self-condensation of vapour in the divergent part of nozzle causes a jump in the flow. In order to determine the ability of this method to predict the condensation zone, a steady solution is obtained for a nozzle under supersonic flow condition and compaired with measurements. The work will be extended to predict the location of condensation jump in steam turbines.
