Résumé

A model is developed for prediction of the nucleate boiling coefficient as a function of the bubble dynamics characteristics (nucleation site density, bubble departure diameter and bubble frequency). The model includes the effects of transient convection to the liquid, as a result of convection in the wake of the departing bubbles. The predicted heat transfer coefficient is compared using data for R11 and R123, and good agreement is found. The model shows that the contribution of transient conduction is small compared to transient micro-convection.
