摘要
一、前言 随着粘性流动计算方法的发展,与叶栅正问题解法一样,叶栅的反问题解法也存在一个如何考虑粘性影响的问题。在粘性流动的正问题解法中,国内外通常采用的有两种方法,一种是全流场求解Navier-Stokes方程,另一种是无粘主流区和边界层的相互迭代。由于直至今日尚未有一种完善的湍流模型。
Based on the algorithms for the inviscid inverse problem and the viscous direct problem, a numerical method for solving the viscous inverse problem of cascades is presented. In the pre-sent work, the given presace condition of viscous inverse problem is transfered into the velo-city distribution in inviscid calculation along the displacement surface which is the new boundary of profile with the addition of boundary layer displacement thickness. An iterative computation process is performed by solving both inviscid inverse problem and viscous direct problem and adopting appropriate relaxation treatment.
