Abstract

An improved two-dimensional space-time conservation element and solution element (CE/SE) method with second-order accuracy is proposed, examined and extended to simulate the detonation propagations using detailed chemical reaction models. The numerical results of planar and cellular detonation are compared with corresponding results by the Chapman--Jouguet theory and experiments, and prove that the method is a new reliable way for numerical simulations of detonation propagation.
