本文讨论了垂直有限平板自由对流问题的Navier-Stokes方程和能量方程的渐近解。用匹配渐近展开法研究了边界层与外流的干扰。借助于变形的纵坐标分析了前缘的影响。在两层边界层模型的范围内，研究了平板后缘附近的流动结构和换热。研究发现，尾流对平板边界层的影响是通过外流来体现的。的解决方案的结果已被支持的速度和温度分布和传热系数的实验数据的情况下的第一类边界条件的板和恒定的热通量的情况下。
An asymptotic solution of the Navier-Stokes and energy equations for the problem of free convection from a vertical finite plate is considered. Boundary-layer interaction with the external flow is studied by the method of matched asymptotic expansions. The effect of the leading edge has been analysed with the aid of a deformed longitudinal coordinate. The flow structure and heat transfer in the vicinity of the trailing edge of the plate are studied within the confines of the two-layer boundary-layer model. It is found that the wake effect on the boundary layer at the plate is manifested through the external flow. The solution results have been supported by experimental data on the velocity and temperature profiles and on heat transfer coefficients both in the case of the first-kind boundary conditions for the plate and in the case of constant heat flux.
