建立了溴化锂吸收式制冷机降膜式发生器水平圆管外滴状布液降膜流动的数学物理模型，通过计算得到了滴状布液降膜流动的液膜厚度和流动速度沿圆周方向的分布情况，为传热传质研究提供了基础。模型中考虑了液膜流动的初速以及液滴与管顶部碰撞的影响，计算所得的液膜厚度分布比Nusselt膜型更加合乎实际情况。
The mathematical physics model of falling film flow outside the drop tube generator in the falling film generator of lithium bromide absorption chiller was established. The thickness of the drop film flow and the flow velocity in the circumferential direction Distribution, for the heat and mass transfer provides the basis for the study. In the model, the initial velocity of the liquid film and the impact of the droplet colliding with the top of the tube are considered. The calculated thickness distribution of the liquid film is more realistic than that of the Nusselt film.
