本文对两股亚音速平行气流在收敛通道中的汇合引起的复合阻塞进行了实验研究，研究了不同的上游滞止压力与出口静压之比。用纹影法进行了光学观测和压力测量。采用考虑两股气流混合的简单流动模型，计算了在出口处发生复合扼流时，收缩通道两端的临界压比。计算结果与实验数据吻合较好。
The compound choking by confluence of two subsonic and parallel streams through a converging duct is experimentally investigated for various ratios of the upstream stagnation pressure to the static pressure at the duct exit. The optical observations by schlieren method are carried out as well as the pressure measurements. The critical pressure ratio across the converging duct when the compound choking occurs at the duct exit is calculated by a simple flow model where the mixing of the two streams is taken into consideration. The calculated results agree well with the present experimental data.
