Abstract
The thermofluid dynamics of pool boiling heat transfer was theoretically studied. A two-phase flow integral model was formulated for the local boiling field adjacent to the heated wall. A set of three non-linear differential equations model the dynamics of the localized void fraction, bubble number density and vapor velocity. The boiling crisis at the critical heat flux is described as a dynamic transition caused by the competition of bubbles coalescence and breakup mechanisms. An analysis of a case of pool boiling in water is presented, showing the consistency of the formulation. The model has potential applications to thermal management of electronic microchips and devices for space environments.
