Abstract

A simple integral method has been developed for laminar film condensation on plane and axisymmetric bodies. The method retains the acceleration terms in the momentum equation so as to account for the Prandtl number effect. The results appear to be in close accord with those of the complete boundary layer equations. The discussions extend over a wide range of Prandtl numbers and the temperature difference across the film, with an emphasis on the low Prandtl number case.

平面和轴对称物体层流膜凝结的积分方法
提出了一种计算平面和轴对称物体层流膜凝结的简单积分方法。该方法保留了动量方程中的加速度项,以便考虑普朗特数效应。所得结果与完整边界层方程的结果基本一致。讨论了普朗特数和膜上温差的广泛范围,重点讨论了普朗特数低的情况。
