Bubble dynamics and mechanistic boiling heat transfer prediction on a scored copper surface
(2021) 8th European Thermal Sciences Conference, EUROTHERM 2021 In Journal of Physics: Conference Series 2116.- Abstract
In this study, pool boiling heat transfer of de-ionized water was experimentally studied on a scored copper surface at a heat-flux range of 0 - 60 W/cm2. Bubble dynamics in an isolated bubble region were carefully investigated, including bubble departure diameters, bubble departure frequencies, and active nucleation site densities. The bubble dynamics were compared with available models, indicating the suitable models regarding the present experimental results. Then, based on the bubble dynamics, a mechanistic heat transfer model, developed in our previous studies, was employed to predict the present boiling curve. In the mechanistic model, heat fluxes from natural convection, transient heat conduction, and microlayer... (More)

In the mechanistic model, heat fluxes from natural convection, transient heat conduction, and microlayer evaporation were incorporated.
