本文研究利用稳流试验台上测出的进气道特性参数,予测发动机压缩上止点燃烧室内的气流速度分布的方法;分析了压缩上止点旋流动量矩强烈衰减的原因,并给出相应的计算公式;广泛的试验结果对比证实了上述计算方法是有效的,并且是有价值的。
In this paper, the method of predicting the gas velocity distribution in the top dead center of the compression chamber is studied by using the inlet characteristic parameters measured on the steady flow test rig. The reasons for the strong decay of the momentum moment at the compression top dead center are analyzed. The corresponding calculation formula is obtained. Extensive experimental results confirm that the above calculation method is effective and valuable.
