The pressure drop of airflow consisting of pressure drop of the perforated plate and liquid-layer is mainly influenced by the plate dimension and bare tower velocity, with the increasing of bare tower velocity, pressure drop of the perforated plate increases. The experimental data are used to develop a correlation as follows:ΔpD＝1.04×10－82g This correlation should be used whenβ＜5％,0.299m/s＜u＜

空气流动的阻力主要由孔板阻力和液层阻力组成，孔板阻力主要受多孔板的几何尺寸及空塔速度的影响，空塔速度越大，孔板阻力越大，对实验数据进行回归分析得出的实验关联式为：ΔpD＝1.04×10－82g 公式适用范围：β＜5％，0.299m/s＜u＜

And the pressure drop of liquid-layer is mainly influenced by weir height. With the increasing of weir height, the pressure drop increases.

And it was considered that plate geometries、weir height、bare tower velocity and heat flux density would affect the heat transfer coefficient.

而液层阻力主要受堰高的影响，堰高越高，液层阻力越大，与空塔速度和孔板的几何尺寸无关，对以往的公式进行修正后得到实验关联式如下：ΔpL＝3911Z 本文对加热管外壁与冷却水之间的换热系数进行了分析，认为孔板的几何尺寸、堰高、空塔速度以及热流密度均会影响换热系数。
