含铝凝胶燃料脉冲爆轰发动机工作过程瞬态特性
Transient characteristics for working process of pulse detonation engine with aluminized gelled fuels
摘要
Abstract
In order to understand the transient mechanism of pulse detonation engine with gelled fuels during the working process,the mathematical and physical model of pulse detonation engine with aluminized gelled fuels was established.The flow field of a single cycle pulse detonation engine with aluminized gelled fuels was simulated numerically by using the conservation element and solution element method,and the transient characteristics during the detonation reaction and impulse generation processes were analyzed.The calculation results show that the strip of the aluminized gelled fuels droplet under the detonation wave is predominant. The aluminum particles scatter into the detonation tube accompanying with the strip of droplets,and participate in reaction,so the a⁃luminum quantity accumulated in the final stage is small.And the process of the gelled fuels'detonation exhaust can be divided into three typical stages,which are expansion stage attached to detonation,gas"choked" expansion stage and weaken expansion stage in sequence.The results have some significant references for application research on pulse detonation engine with gelled fuels.关键词
