Radial Nozzles for Non-Cavitating Flow of Water at High Pressure Drops

摘要

We analyze the conditions under which radial nozzles can be used to measure or regulate the flow of water at high pressure drops. Using the URANS model, numerical simulation of water flow in radial nozzles was carried out. We find a dependence that establishes a relationship between the minimum static pressure on the geometric contour of a radial nozzle and the pressure drop across the nozzle, which leads to an estimate of conditions for the onset of cavitation.
