项目摘要
1. A discharging method of high pressure exhaust gas by measn of a chock wave confinement in a duct been developed. The duct, which is conneted to an exhaust gas pipe, has inlet and exit orifices so that the flow is foubly chokes at these sections.2. For analytical purposes, the flow in the duct is assumed to be a frictional and adiabatic flow with a normal shock wave. The calculated results show that the total pressure reduction increases with a decreasing opening area of the inlet orifice, and the shock wave confinement in the duct can be achieved by cesreasing the opening area of the exit orifice.3. An apparatus for confinement of a shock wave, whick is generated by an expansion of hihg pressure exhaust ga, has benn constructred and tested over a wide range of pressure tations across the duct. The location of the shock wave in the duct agrees well with the calculated results. On the ogher hand, the trotal pressure loss actoss the duct is much larger than the calculated values, becouse the schok becomes a presudo-shock.4. The theoretical and experimantal results mentioned above indicate the validity of the present discharging method, and the present method is quite useful for controlling and discharaging og high pressure exhause ga. The data for shock wave confinement have been obrained.
1.提出了一种利用阻塞波在管道中限制高压废气排放的方法。连接到废气管道的管道有入口和出口孔口,因此气流在这些区段被完全堵塞。为便于分析,假定管道中的流动为具有正激波的摩擦绝热流动。计算结果表明,总压降值随进气孔开口面积的减小而增大,通过增大出口孔的开口面积可以实现激波在通道中的约束。一种用于限制冲击波的装置,它是由高压废气的膨胀产生的,已经在管道上的大范围压力变化下进行了建造和测试。激波在管道中的位置与计算结果吻合较好。另一方面,导管上的压力损失比计算值大得多,这是因为管道中的缝隙变成了前震。上述理论和实验结果表明,本文提出的排气方法是有效的,对高压排气的控制和排气具有一定的实用价值。获得了冲击波约束的数据。
