| 摘 要： | 本文从可压缩流的基本理论出发,讨论了等截面套管喷枪的计算原则和方法,并对它的气体力学参数进行了测试。测定了不同管径的不锈钢管和铜管的摩擦阻力系数。在此基础上,对套管喷枪出口断面上的速度分布和沿套管喷枪轴线上的速度变化规律和压力变化规律进行了测定。通过试验证明了测定的摩擦阻力系数是可信的,拟定的计算方法是实用的。

| Abstract: | The computation principle for the pipe-casing gun of the equal acress-section area is studied by applying the basic theory of compressible. The aerodynamic parameter of the pipecasing gun and the friction factor of rustless sted-pipes and copper-pipes of different diameters are measured. On the basis of this measurement, the outlet-velcity profile and the change of the rate and pressure on the axis are measured. The results show that the friction factor measured is reliable and the computation method is practical. |
