| 摘 要： | 应用CE/SE方法对气液两相爆轰进行数值求解,研究了爆轰波在管内的传播过程.对刚性源相,采用四阶龙格库塔法对其求解.分析了液滴半径大小对爆轰波峰值压力的影响,液滴半径增大,爆轰压力减小,形成稳定爆轰波的距离增加;且液滴半径过大不能形成稳定的爆轰波.

| Abstract: | Gas-Droplets Two Phase Detonation is numerically solved with CE/SE method.The source items are calculated by the fourth-order Runge-Kutta method.The effects of different size of the droplets on the detonation pressure are studied.The larger the size of droplets,the smaller detonation pressure,the longer distance to get the fully developed detonation.If the size of droplet radius is too large,the stable detonation cannot be formed. |
