【摘要】 本文建立了三维对流扩散方程的混合有限分析八点隐格式，并证明了它的基本数学性质。应用原函数法和交错网格技术给出了三维Ｎ—Ｓ方程的混合有限分析解法，计算了雷诺数Ｒｅ＝２０、５０和１００三种情况下的三维方腔内的流场，结果与已有计算成果一致。更多还原

【Abstract】 A Hybrid Finite Analytic Implicit 7-points scheme is established for 3-D convection-diffusion equation and its basic mathematical propertied are proved in this paper.For 3-D N-S equation, The calculational method of HFAM in primary variable and staggered grid is given. As an example, the calculation for 3-D cavity flow is made for Re = 20, 50 and 100.The calculated results quite agree with that existed.更多还原
