Numerical simulation of detonation wave with finite spectral ENO scheme

High order finite spectral ENO scheme and two-step reaction model are used to simulate nonsteady detonation waves of stoichiometric hydrogen-oxygen mixture in order to study the development of transverse waves and the evolution of triple-shock waves. Finer structures of detonation waves were simulated and the mechanism of collision and submergence of triple-shock waves were discussed. The obtained characteristics of detonation waves are in good agreement with previous numerical and experimental results. Study shows that high order finite spectral ENO scheme can be used to simulate detonation waves.EI04343-3482
