摘要
本文首先对旋转的任意旋成面上的理想可压缩流动引入一新通用函数——矩函数,并论证它的主要性质,接着将它推广到粘性气体的情况。然后,提出一个基于矩函数的旋成面叶栅气动反命题及A型杂交命题的通用解法。研究表明,矩函数对求解杂交命题(反命题是其特例)和跨声速流动具有明显的优越性。
A new general function - moment function - for ideal compressible flow along an arbitrary rotating streamsheet of revolution is introduced first, and furthermore, generalized to viscous flows. Finally, based on it, a universal method for solving inverse- & hybrid (type A, [2]) aerodynamic problems of airfoil cascades on a general streamsheet of revolution is proposed. It has been shown that the new function possesses some remarkable characteristics which make it particularly suitable for solving hybrid problems and to transonic flow. The possibility of an extension of moment function to full 3-D. viscous compressible flow is also indicated [8].
