提出一种带有喷管结构的新型点火管。根据该点火管的结构特征和工作特点,建立了点火管内两相流数学模型。通过数值计算,分析这种点火管的工作特性。计算结果与试验结果之间的一致性程度较为理想。实验与数值分析表明:这种新型的点火系统对抑制压力波有明显的作用。
A new type of ignition pipe with nozzle structure is proposed. According to the structural characteristics and operating characteristics of the ignition tube, a mathematical model of two-phase flow in the ignition tube was established. Through numerical calculation, analysis of the working characteristics of this tube. The degree of consistency between the calculated results and the experimental results is ideal. Experimental and numerical analysis shows that this new type of ignition system has a significant effect on suppression of pressure waves.
