Numerical simulations of the interaction between the shock waves and moving interfaces
It is a crucial problem in the studies of the fluid on numerical simulations of the interfaces movement in multi-component fluids. Fluid dynamic characteristics are studied during shock waves pass helium bubble in this paper. These methods are used including high resolution discontinuous finite method for Fluid dynamic equations. Level set method for capturing moving interfaces and ghost fluid method with Isobaric fix for disposing the interfaces, which obtains profiles of the helium bubble, density contours and the curves of density and pressure with center axial direction. It is in good agreement for the general bubble shape and position compared with those in other numerical schemes.
