Abstract
According to the experiment results of steam-water two-phase flow in variable channel (steam injector), the relationships among the outlet pressure of water nozzle and the inlet low-pressure water temperature, flow flux, or the water temperature rise are quantitatively studied. The mathematical formula for the outlet pressure of water nozzle is obtained. Then the pressure-lifting performance calculation model of supersonic steam-water two-phase flow in variable channel is developed. The error between the calculation result using this model and the experiment result is less than 10%. These are beneficial to the development of the lifting pressure technology with supersonic two-phase flow in channel of variable section.
