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 the main aerodynamic performance parameters such as suction coefficient, loss coefficient and momentum correction coefficient of exhaust injection system under the condition of uneven inlet and outlet air flow and frictional loss between air flow and mixed tube wall are derived. The results calculated by these expressions are in good agreement with the experimental results.
