摘要
导出了在进出口气流不均匀及气流与混合管壁面间存在摩擦损失的条件下,排气引射系统的抽吸系数、损失系数及动量修正系数等主要气动性能参数的表达式。由这些表达式计算出来的结果与试验结果吻合良好。
The expressions of pumping coefficient, loss coefficient and momentum correction factor of exhaust ejector systems are presented considering the effect of non-uniformity of gas flow and friction loss on the systems. Comparing the results from the expressions with those of experiment, it can be concluded that the expressions can be used for the optimal design of exhaust ejector systems.
