ABSTRACT

A theoretical analysis of film condensation on profiled surface elements is presented when liquid film is subject to suction. Such a case occurs for condensa-tion in conditions of lowered gravitation, as well as in ground conditions subject to intensive mechanical or capillary suction, when the gravitational forces do not appear, or is created by suction not influencing directly the film flow on the con-densation surface. The mathematical model including a one-dimensional differ-ential equation describing the conservation of mass, momentum and every on the condensation surface. In the case of condensation on a non-isothermal surfaces model in addition includes a heat conductivity differential equation for the wall. A numerical analysis of this equation system is done. It is shown that a consider¬able and non-monotonic change of film thickness and pressure gradient in the film arises when intensive suction takes place. Such non-uniformity leads to the conclusion that there are limited opportunities of heat exchange enhancement for the condensation with liquid film suction.
