| Popis: | The purpose of this study is to analyse the combined heat and mass transfer of liquid film condensation from vapour-gas mixtures flowing downward along an inclined channel. Both the liquid and mixture regions are approached by two-coupled laminar boundary layer. The model uses an implicit finite difference method to solve the coupled governing equations for liquid film and gas flow together with the interfacial matching conditions. The effects of the inlet to the wall temperature difference, the inlet Reynolds number, the inlet relative humidity and the angle of declination on the condensation process are examined. |
