Numerical modelling of condensation phenomena for subcooled flow boiling applications

A methodology is presented for the investigation of the hydrodynamic and heat transfer effects of subcooled flow boiling phenomena. We employ interface capturing simulation with mechanistic calculation of the local rate of phase change. The numerical accuracy of the methodology is demonstrated for the modelling of condensation, by considering the case of heat-controlled collapse of a spherical vapour bubble surrounded by subcooled water. Our results demonstrate excellent agreement with the analytical solution.
