Abstract

Due to excessive stress in the orifice, cavitation occurs in high-pressure Diesel injectors. As experiments are very hard to manage for injection conditions (small-scaled, high-speed flow), a numerical model seems to be the right tool to get a better understanding of the flow features inside and at the exit of the injector nozzle. The purpose of this paper is to present a simulation code based on a Homogeneous Equilibrium Model. The validation of the code for typical cavitating flow configuration is presented. Then numerical results of cavitating flows in Diesel injectors are shown. Then we report concluding remarks and objectives.
