【摘要】 在Stodola滑移系数预测公式的基础上 ,利用射流—尾流模型和有效弯线的概念 ,借鉴文献[2 ]中Senoo等人修正该公式采用的一些思想方法 ,提出了流场阻塞效应、有效弯线与几何弯线偏移和壁面摩擦效应对滑移系数的影响原理 ,并给出了相的修正公式 ,从而提高了滑移系数的预测精度。更多还原

【Abstract】 On the basis of Stolola slip factor equation and Senoo’s thinking way in reference,this paper uses jet_wake flow model,considers that flow passage blockage,variation of effective camber line and friction force on the inner wall are main causes which effect slip factor,and find a modificative equation to express those effects. After experiment,the modificative equation is much better than Stodola equation.更多还原
