Heat and Mass Transfer During Condensation

Condensation heat transfer is an important, fundamental thermal-hydraulic process that is relevant to many industrial applications. As the case of runoff, heating and / or cooling, concentration of dilute solutions and in refrigeration. This work aims to understand at first, the phenomena that characterize the coupled transfer of heat and mass during the film condensation of pure fluid such as R134a and water vapor in the presence air (noncondensable gas). Then there is the study of the condensation of a ternary mixture (alcohol-alcohol, alcohol-water) in the presence of noncondensable gas. There is also the film condensation of a condensable gas within a porous wall channel. In the porous medium, the flow is described by the model of Darcy-Brinkman-Forchheimer. The goal is to provide relevant information by examining the influence of various system parameters.
