Description

This example features both a 2D input deck and a 3D input deck. In the 2D cavitation problem, we test a cavitation model implemented in the dual CESE solver (Please note,  this cavitation model has previously been implemented in the regular CESE solver). The cavitation model  used is Schmidt’s homogeneous equilibrium model^[1] (HEM), which is based on the acoustic speed of the mixture of liquid and vapor. This model is simple but contains the important characteristic information of cavitating flows. This cavitation model is very suitable for high-speed flows in small geometry, like diesel injection systems. In the 3D cavitation problem, the 2D cavitation in a non-hydro nozzle model is extended to a 3D cylinder shape non-hydro nozzle.
