Finite Volume simulation of cavitating flows
Résumé
In this work, we propose a numerical method for the modelling of phase transitions in compressible fluid flows. The pressure laws taking into account phase transitions are complex and lead to difficulties such as the non-uniqueness of the entropy solutions. In order to avoid these difficulties, we propose a projection finite volume scheme. It is based on a Riemann solver with a simpler pressure law and an entropy maximization procedure in order to recover the original complex pressure law. Several numerical experiments are presented which validate this approach.
