چکیده
In this study, numerical simulations of a vapor bubble in subcooled pool boiling have been performed. The applied numerical procedure coupling level-set function with moving mesh method has been validated by comparing the results of bubble-growth history including bubble departure diameter with data from experiments. The predictions of bubble dynamics and heat transfer for various subcoolings as well as different gravity levels are presented. DOI: 10.1115/1.4002093

Numerical Simulation of Dynamics and Heat Transfer Associated With a Single Bubble in Subcooled Boiling and in the Presence of Noncondensables
During phase change at the bubble-liquid interface, under subcooled boiling conditions, noncondensable gases dissolved in the liquid will be injected into the bubble along with vapor. Due to heat transfer into subcooled liquid, vapor will condense in the upper regions of the bubble while noncondensables will continue to accumulate. Subsequently, thermocapillary convection caused by nonuniform s...
