WebPool boiling is defined as boiling from a heated surface submerged in a large volume of stagnant liquid. This liquid may be at its boiling point, in which case the term saturated pool boiling is employed, or below its boiling point, when the term subcooled pool boilingis … WebTwo-phase heat transfer processes such as boiling are required to address waste heat management challenges. Among the various regimes, the nucleate boiling regime, which relies on the ebullition cycle to dissipate large amounts of heat within narrow temperature budgets is desired in such applications.
