Modeling of Cavitation

The paper deals with the study of source terms for Euler and Navier-Stokes equations which describe cavitation phenomena in one- and three-dimensional flow. Cavitation occurs in many technical applications, such as injectors, throttles and pumps. The modeling of cavitation is a challenge due to the complex structure of the cavitation process and the difficult numerical realization. The main problem is to simulate one- or three-dimensional flow in order to predict the material of cavitation erosion or to determine the mass flow which will be limited if cavitation occurs in a throttle.
