shock w ave flame stab ilit
U sing a horizontal shock tube o f 4. 8m length and 60mm ×60mm section area, experimen ts on the interaction of shockw ave and flam ew ere perform ed and some shadowg raphsw ere successfu lly acqu ired by aYA-16 high-speed camera. The shadowg raphs show ed the instab ility, d istortion and breakup of the flam e. Based on the Navier-S tokes equations coupled w ith the chem ical reaction term s, some relevan t thermodynam ic and k ine tic da ta and modif ied Van Leer sp litting schem e, the interaction process o f the shock w ave and the flame w as simu lated. From the resu lts, the flame stability and themechanism o f vortex formation w ere discussed. The experimental results w ere in good agreement w ith the calcu la ted resu lts.
