AUTHORS | Michael Herty, Siegfried Müller, Aleksey Sikstel |
ABSTRACT | Modelling of cavitation phenomena requires coupling of models for fluid and solid materials. For this purpose we extend a strategy based on the solution of coupled Riemann problems, proposed in [9]. The coupling strategy for the case of perfect gas equation of state has been established and validated in [8]. In this work we include the case of a stiffened gas and derive conditions under which there exists a unique solution to coupled Riemann problems. |
