Contrast study on cold - flow mixing effect and combustion efficiency of afterburning chamber of solid rocket ramjet 固冲发动机补燃室冷流掺混效果与燃烧效率对比研究
The numerical simulation of the motor cold flow field and the mixing process of various kinds of gases are performed by piso algorithm 采用piso算法模拟了冷流状态下发动机的内流场和各种气体组分的相互掺混过程。
The experimental results show that adiabatic efficiency has a remarkable improvement in low cold mass flow ratios , adiabatic efficiency can improve by 30 % in the best condition 实验表明,在冷流率小的情况下,通过加湿可以使得绝热效率得到显著的提高,最好可以提高30 。
