Abstract
As an application to a propulsion system such a pulse detonation engine,many experimental studies on detonation have been performed.However,these are difficult to catch the chemical species which participates in ignition and extinction,because only surface behavior can be observed in almost experiments.The present study by numerical analysis in three dimensional elucidates the internal action of shock triple points which take part in the propagation of detonation,and examines what kind of chemical species would exert effectively on the action of the shock triple points.The used numerical method is the semi-implicit MacCormack-TVD scheme with the second order accuracy.
