A High-resolution Method for Realistic Detonation Structure Simulation

Detonation simulation is one of the computationally most challenging hyperbolic problems of practical interest. The source terms from detailed non-equilibrium chemistry are usually stiff and introduce non-neglectable scales typically not present in purely hydrodynamic calculations. This paper outlines all components of an efficient solution strategy. Emphasis is put on the description of the employed shock-capturing scheme and the necessary extensions of the underlying approximative Riemann solver for thermally perfect multi-component Euler equations. Computational results confirm effectiveness and relevancy of the approach.
