The Numerical Study of a Dropwise Condensation Mode when Cooling Heat Transfer Surfaces

Abstract:

A two-dimensional nonstationary model of calculation of heat transfer at viscous fluid droplet spreading over the heated substrate is presented. A process of the fixed droplet spreading over a simple geometry substrate has been calculated. A hydrodynamic picture of the process of spreading has been obtained. The influence of the parameters of the model on the nature of spreading has been studied. The temperature profiles at the droplet surface have been obtained. The setting time of the stationary mode has been evaluated.
