摘要
本文提出了一种在S_1流面上进行势流与粘性流迭代求解弦向缝隙叶栅流场的计算方法,将S_1流面上势流方程组的解与经Illingworth-Stewartson变换后的边界层方程结合起来联立求解弦向缝隙叶栅流场。计算值同实验结果相当吻合,在正大攻角时,弦向缝隙叶栅能有效地控制边界层分离。
This paper sets faith a method of calculation by iterating the potential flow and viscous flow on S1 stream-sheet to solve the flowfield of the cascade with chordwise-split blades. It can get the solution of the flowfield of the cascade with chordwise-split blades by means of combining the potential equations on S1 stream-sheet and boundary layer equations by Illingworth-Stewartson transformation, the agreement between the calculation and experiment data is good. The cascade with chordwise-split blades can effectively control the boundary layer separation at positive angles of attack.
