摘　　要：本文分析了气流引射器混合室内射流的紊流混合过程,速度分布、温度分布采用阿勃拉莫维奇的普遍参数型,建立起求解流场的积分方程。验算了等截面管道中非均能气流的混合过程,温度分布与实验作了比较,还对某气流引射器混合室流场进行了计算,给出若干截面上的速度分布及压强沿轴向的变化规律。Upon an analysis for turbulent jet mixing process in the mixing chamber of ejector, the hypothesis of universal ejection characteristics developed by Abramovich is used to build up the integral equa- tions. To verigy the integral method, two samples of non-isoenergetic turbulent flow mixing in a con- stant area duct are computed and the temperature profiles are compared with the experimental data. The flow field in the mixing chamber of an ejector is also calculated to present the velocity distribution at several locations and pressure variations along the axis.
