| 摘 要： | 采用高速摄影技术拍摄了等当量比的甲烷/空气预混气环境下,火焰与激波相互作用的时序照片,对实验结果进行了分析讨论。使用基于带化学反应的N-S方程和热力学数据,利用改进的VLS格式,对等当量比条件下甲烷/空气预混气中激波与火焰的相互作用进行了数值模拟,并利用光学知识,进行了计算光学的数值模拟。实验结果与数值计算结果进行了比较,两者符合得较好。

| Abstract: | Using high-speed photograph technique, a series of experimental pictures of interaction between shock wave and flame for stoichiometric methane/air premixed gas were recorded. The experimental results were discussed. Based on the N-S equations coupling with chemical reaction, the phenomena of shock wave and flame interaction in the methane/air premixed system are numerically studied by using modified VLS scheme. And the pictures of computational optics were obtained using the refractive optics. The experimental results were compared with the calculated results, and the agreements were obtained. |
