Abstract

The stationary flow of a bubble gas-liquid mixture in a nozzle of circular cross-section is considered. The possibility of realizing superhigh temperatures and pressures in the gas phase at the nozzle site near the minimum cross section is analyzed. The effect of the parameters (the initial radius and the volume content of bubbles that determine the composition of the volume flow of liquid fed into the nozzle) on the flow pattern is studied.
