Hydrodynamics of Flow of Two-Component Mixtures in Nozzles

The paper considers the hydrodynamics of a two-component mixture of a liquid and a gaseous metal flowing through accelerating and condensing nozzles. The effect of the rate of heat exchange and condensation on the flow, the conditions for optimum acceleration of the mixture and for optimum slip of the liquid component relative to the metal vapours are discussed. Various ratios of velocity to nozzle cross-section are considered for different conditions of heat exchange and rate of change in the cross-section. The paper also discusses shock waves and condensation jumps, their structure and the conditions under which they occur. (author)
