This tutorial examines the pressure-driven cavitating flow of waterthrough a sharp-edged orifice. This is a typical configuration in fuel injectors,and brings a challenge to the physics and numerics of cavitation models, because ofthe high pressure differentials involved, and the high ratio of liquid to vapor density.Using FLUENT’s multiphase modeling capability, you will be able to predictthe strong cavitation near the orifice after flow separation at a sharp edge.
