In recent years, researchers have directed their studies towards solutions aimed at enhancing heat exchangers effectiveness. In this context, dropwise condensation (DWC) has been identified among the most promising solutions to increase the condensation heat transfer coefficient (HTC). In fact, DWC provides heat transfer coefficients up to ten time...

Dropwise condensation is a quasi-cyclic process characterized by the nucleation, growth, and removal of discrete liquid droplets on a subcooled surface. The removal of condensate is a critical aspect, usually achieved by exploiting the gravity force, the drag force of vapor or the surface wettability gradient. This paper presents an experimental st...

When a pure vapor condenses over a surface, it can form a continuous liquid film or a multitude of discrete droplets, thus realizing the so-called dropwise condensation (DWC). In the literature, most of the experimental data refer to DWC on vertical condensing surfaces with quiescent vapor. However, in many applications, the condensing vapor usuall...

Dropwise condensation (DWC) is a leading topic in the research concerning two-phase heat transfer, since it has been identified as a passive solution to enhance the efficiency of the condensation process. In the literature, there are already several works investigating dropwise condensation of pure quiescent steam. However, the effect of vapor velo...

With this poster, an experimental comparison between dropwise condensation occuring on both vertical and horizzontal surface has been introduced. The experimental data were compared with a new model based on population balance theory. Finally, a new individual-based model developed using hybrid MATLAB and C codes was introduced.
