Influence of rarefaction wave on premixed flame structure and propagation behavior

To explore the influence of rarefaction wave on the structure and propagation behavior of the premixed propane/air flame in a rectangle combustion pipe, the techniques of high speed Schlieren photograph method, pressure measurement and so on are used to study the interaction processes between rarefaction wave and flame. Two cases of rarefaction wave-flame interaction were performed in the experiment. The experimental result shows that both the rarefaction waves can cause the flame transition from laminar to turbulent combustion quickly. The cowflow rarefaction wave decreases the flame speed, while the counterflow rarefaction wave leads the flame propagation speed to increasing on the whole, accompanied with sharp vibration.     

二维楔形体入水砰击仿真研究

基于数值仿真的方法对二维刚性楔形体的入水砰击问题进行了研究.建立了包含气水流场的二维有限元模型,考虑空气、重力等因素在砰击过程中的影响,研究了流场的自由液面、压力和速度等物理量的变化情况.对不同入水角的楔形体入水的砰击压力峰值系数进行了计算,分析压力峰值的变化规律.结果表明,楔形体入水砰击压力峰值系数不仅与入水角度有关,而且与入水速度也有很大的关系.
