WebJan 9, 2024 · Condensation heat transfer is a vital process for a plethora of industrial application. Dropwise condensation of steam on hydrophobic polymers, typified by the formation of discrete water droplets which shed and clear the surface for re-nucleation, has a 10X higher heat transfer coefficient when compared to filmwise condensation on bare … WebFeb 1, 2024 · We study the dynamics of vapor condensation and fluid evaporation governed by a one-sided model in a low-Reynolds-number lubrication approximation incorporating surface tension, intermolecular effects, and evaporative fluxes. Parameter ranges for evaporation-dominated and condensation-dominated regimes and a critical …
