将通过转动叶栅的定常的相对流动和通过静止叶栅的定常的绝对流动相连接,作为统一流场求解.这样在实际的压气机和透平的计算中与S,配合,可以组成多排叶片的同时统一计算,得出多排叶片的准三元和全三元分析计算与设计. 在计算中,采用了广义的Kutta-Jukowsky条件.对最后一排叶片的出气角,中间叶栅的流函数值进行调整.实际计算表明,这种调整是敏感和有效的.计算结果表明:相对于不定常计算,计算比较简单,可供工程使用. The constant relative flow through the rotating cascade is connected to the constant absolute flow through the stationary cascade and solved as a unified flow field so that in actual compressor and turbine calculations it can be combined with S to form multiple rows In the calculation, a generalized Kutta-Jukowsky condition is adopted. For the exit angles of the last row of blades, the middle cascade The flow function value is adjusted.The practical calculation shows that this kind of adjustment is sensitive and effective.The calculation results show that the calculation is relatively simple and can be used by the engineering as compared with the unsteady calculation.
