基于边界层理论和完整的边界条件，采用Collocation方法，推导出了沿倾斜壁面下降的在蒸发、等温和冷凝状态下普通适用的二维降膜拜表面波扰动时域演化方程， 并分析了不同因素的影响。结果表明：蒸发不利于稳定，冷凝有利于稳定， 在蒸发状态下，热毛细力导致其失稳，在冷凝状态下，则促进其稳定；表面张力不从有促进流动稳定的作用，液膜的稳定性随倾角和雷诺数的增大逐渐减小，随Ka数的增大逐渐加强；在小雷诺数下，液膜的稳定性主要取决于蒸汽压力和热毛细力的变化，在高雷诺数下，则取决于惯性力；流体物性和壁面倾角在一整个雷诺数范围内对液、膜的稳定性起着非常重要的作用。

The evolution of the suface waves for vertical free-falling films with Reynolds number ranging from 400to 5,100 was measured using multiple-point conint conductance sensors and a computer-based data acquisition system. The Physieal and mathematieal models describing the free-falling turbulent wavy films with the free surface boundary are presented. The governing equations are solved numerically in the film waves based on the coordinate transformation of the measured time-dependent film thickess data. The results show that the evolution of the surface waves has a remarkably nonlinear nature. The hydyrodnamics and velocity profiles at the wave front, the wave crest, and the wave back for the soliary waves indicate significant effects of the soliary surface waves with interior reeirculation flow on heat and mass transfer enhancement. A correlation for an average heat transfer coefficient is proposed as a function of the Reynolds and Prandtl numbers based on the measurements.
