Abstract

The effect of the initial humidity of a two-phase flow on the aerodynamic characteristics of a diffuser is considered. A series of calculations is carried out which permit the pressure distribution in the diffuser to be investigated in the case of change of the initial flow velocity, coefficient of slip of the phases, and the initial humidity of the flow. It is shown that, with increase of the initial humidity in the diffuser, there appears a sharply expressed region which has a negative pressure gradient, where the steam velocity can reach the critical value. The numerical solution is compared with the experimental results.
