Abstract
Flow pattern and heat and mass transfer characteristics for a filmflowing over a vertical wavy column are numerically investigated in a laminar flow regime. In our approach, the heat and mass transfer coeffcients are avoided in order to include hydrodynamics directly in the heat and mass transfer rates. As a consequence the numerical model is decomposed into two steps. Firstly, the flow pattern for a ®lm with a free interface is developed. Secondly, heat and mass transfer are investigated with the incorporation of velocity fields. The heat and mass transfer coeffcients increase in
