| 摘 要： | 平壁上等温层流液膜的破裂特性师晋生施明恒（东南大学动力工程系，南京２１００１８）流动液膜传热传质具有流量小、温差小、强度大等独特优点，但在某些条件下，连续流动的液膜会发生破裂，在壁面上形成干区，从而降低传热传质的强度，甚至引起壁面烧毁．所以，对流动...

| Abstract: | The surface energy of liquid solid interface is introduced into the rivulet model of isothermal laminar liquid film flow. The critical characteristics of isothermal laminar liquid film before break up on vertical and horizontal surfaces are investigated. Expressions for the critical film thickness and flow rate are obtained. The effect of the surface roughness on the break up of liquid film is discussed. |

| Keywords: | liquid film rivulet break up surface energy contact angle roughness |
