The Random Projection Method for Stiff Multispecies Detonation Capturing

In this paper we extend the random projection method, proposed for general hyperbolic systems with stiff reaction terms, for underresolved numerical simulation of stiff, inviscid, multispecies detonation waves. The key idea in this method is to randomize the ignition temperatures in suitable domains. Several numerical experiments, in both one and two dimensions, demonstrate the reliability and robustness of this novel method.
