A Low-Mach / Acoustic Solver for Fluid Structure Interaction Problems

Abstract

An all-Mach correction is applied to the HLLC scheme for computing liquid flows described by the Euler equations closed with the stiffened gas EoS. The accuracy provided by the corrected scheme is assessed on a series of model problems : Gresho vortex, low-Mach shock tube and a piston problem providing a simplified description of the bubble expansion occurring in some nuclear safety problems.
