摘要:
在长4.8m、截面为60mm×60mm的卧式激波管中,进行激波与火焰相互作用过程的实验研究。利用YA16高速摄影仪拍摄了该过程的照片,显示了激波作用下火焰的失稳、变形和破碎。基于带化学反应的NavierStokes方程和有关热力学和反应动力学数据,利用改进的VLS格式,对该过程进行了数值模拟。根据实验和数值计算结果,讨论了火焰稳定性和漩涡生成机理,且理论计算与实验结果较为一致。
Abstract:
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.
