摘要
一、二维叶栅正交O型网格的系列保角变换法 1.基本变换过程 变换公式和过程见图1。 在由Ω向ω的变换中,为求待定复常数a、b、c,先令ω(z=±∞)=±1,并定义Ω^+=[g(+∞)]^(1/k),Ω^-=[g(—∞)]^(1/k),由变换ω=(a—bΩ/c)/(1—Ω/c)得b=(—2c+Ω^-+Ω^+)/(Ω^+—Ω^-);a=1—(1—b)Ω^+/c;若r_(max)、r_(min)分别表示边界的最大、最小极径。
The orthogonal O-type grids have been generated by using conformal mapping techniques; A complex technigue for generating partially orthogonal C-type grids has been developed. Furthermore, the suitability of grids to boundary conditions and the influence on the computational accuracy of the flow through cascades have been researched.
