本文解析地研究了各向异性多孔介质中饱和蒸汽沿着垂直表面的稳态膜状冷凝问题。多孔介质的渗透率是各向异性的，其主轴的方向与重力矢量的方向是倾斜的。在广义达西定律的基础上，在边界层近似下，得到了凝结水温度和流动模式的类似解。此外，封闭形式的解决方案的边界层厚度和传热率已获得的控制参数的问题。
This work analytically investigates the problem of steady film condensation along a vertical surface embedded in an anisotropic porous medium filled with a dry saturated vapor. The porous medium is anisotropic in permeability whose principal axes are oriented in a direction which is oblique to the gravity vector. On the basis of the generalized Darcy's law and within the boundary layer approximations, similar solutions have been obtained for the temperature and flow patterns in the condensate. Moreover, closed form solutions for the boundary layer thickness and heat transfer rate have been obtained in terms of the governing parameters of the problem.
