Multi-Dimensional Adaptive Simulation of Shock-Induced Detonation in a Shock Tube (original) (raw)

This paper describes an efficient strategy for solving the Euler gas dynamics equations for mixtures of thermally perfect gases with non-equilibrium reaction chemistry using high resolution versions of Godunov's scheme available in the CLAWPACK suite. The approach uses the Berger-Colella block structured adaptive mesh refinement technique for explicit time-dependent finite volume schemes to overcome the stiffness problem arising from the wide time scales. One-and two-dimensional detonation simulation for the oxyhydrogen reaction mechanism in Cartesian geometry was performed and the strategy for non-equilibrium reaction terms has been outlined.
