毛细表面润湿是一种被动现象，取决于自由表面能。随着传热速率的增加，在一定限度内，更多的液体流到表面上并蒸发。对几种毛细管槽结构，同时求解了描述传质和传热机理的微分方程。此外，通过本文概述的方法，可以隔离和评估固-液-汽夹层传热现象的影响。这不仅提供了一种预测通过毛细槽润湿的表面的表面传热系数的方法，还提供了关于弯月面附着区域附近的传热的基本信息。
Capillary surface wetting is a passive phenomenon that depends on free surface energies. As heat transfer rates increase, within limits, more liquid flows onto the surface and evaporates. The differential equations describing mass and heat transfer mechanisms have been solved simultaneously for several capillary groove configurations. Further, by methods outlined in this paper, the effects of solid-liquid-vapor interline heat transfer phenomena can be isolated and evaluated. Not only does this provide a method for predicting surface heat transfer coefficients for surfaces wetted through capillary grooves, it also provides basic information about heat transfer in the vicinity of the meniscus attachment region.
