摘要 通过对有限容积法界面插值的分析,提出了一种较调和平均法更为直接、更为有效的用于计算控制容积法控制界面参数的插值方法,并给出了调和平均法失效的算例。数值算例表明,本文方法与Kirchhoff变换法相比具有相当的精度,但又不像Kirchhoff变换法那样需要完成大量的积分运算,计算工作量小,简单可靠。 Various interpolation methods for diffusion coefficients at control volume surfaces are briefly discussed and extensively compared with the analytical solutions of both pure diffusion and convection-diffusion problems in this paper. It is found that the harmonic mean method is not as accurate and reliable as it is supposed to be. A new method is thus developed by careful re-examination of the exact meaning of the definition of these control surface diffusion coefficients. The extensive numerical comparisons are given for both the harmonic mean and the present method and the results show that the method proposed in this paper is accurate, reliable and easy to use.
