A numerical Simulation of H₂-O₂-N₂ gaseous detonation based on detailed chemical reaction model

Numerical simulation has been performed to study the cellular detonation wave in a mixture using a detailed chemical reaction model with 12 species and 23 elementary reactions and a fifth-order weighted essentially non-oscillatory (WENO) scheme with a third-order TVD Runge-Kutta time stepping method. We study one-dimensional ZND detonation, the detailed structure of self-sustained detonation and flow structure around a triple point. The simulation results suggest that two-dimensional detonation wave front formations are greatly enhanced by the presence of transverse waves. The motion of transverse waves generates triple points, which cause the detonation propagation to become self-sustained.
