Numerical simulation of flows in detonation engine
The goal of this study is to numerically investigate the flow in a detonation engine. A simplified mathematical model of a two-phase chemical reaction, including the induction period and the subsequent reaction period was used. The gas was assumed to be inviscid, and the one-stage Arrhenius model for chemical reaction rate was employed. Spatial discretization of the fluxes vector normal to the direction of cell boundary is made on the basis of two similar TVD-schemes: the slightly improved version of the Harten scheme and the Chacravarthy - Osher scheme. The suggested algorithm was also used for numerical simulations of flows in channels with constrictions.
