Towards the modelling of fluid-structure interactive lost core deformation in high-pressure die casting

This paper investigates the fluid-structure interaction (FSI) that would be expected to occur when a lost core deforms in high-pressure die casting. A two-phase compressible Volume of Fluid approach is used to model the fluid. The turbulence contribution to the Navier-Stokes equations is accounted for by using the Reynolds-averaged Navier Stokes (RANS) Menter SST k−ω model, whilst an isotropic linear elastic model is assumed for the core...
