Numerical Studies of a Two-Phase Hyperelastic
Model
摘要
Abstract
The paper is devoted to numerical studies of a two-phase hyperbolic model describing thedynamics of hyperelastic media. The model is a generalization of the well-known multivelocityfully nonequilibrium Baer–Nunziato model widely used when describing shock-wave anddetonation processes in multiphase media. The equations of the model are given both in thegeneral and in the spatially one-dimensional cases, and its properties are described. For numericalstudy, the path-conservative HLL method is applied. The numerical study is carried using anumber of test Riemann problems on the decay of a discontinuity.
