Spatial distribution modeling of droplets during water dropwise condensation on textured surfaces

Résumé

The aim of this study is to simulate water droplets spatial distribution on a flat glassy surface under atmospheric pressure. This process has a great importance in analyzing and manufacturing of condensers, heat exchangers and other steam operating devices. In the dropwise condensation there are two main mechanisms for droplet growth. When the droplets are smaller than the half of the mean distance between two drops, they grow by absorbing water molecules from the gas phase, and for droplets bigger than this amount the mechanism is the droplets coalescence which means joining of the neighboring drops to form a new bigger drop. In the current study, the process of dropwise condensation was modeled using a computer program considering both absorption and coalescence. Then the results of this model were compared to experimental results using Ripley function method.
