| dc.description.abstractEn | The boiling crisis (BC) is well known in the world of heat and mass transfer. It is a transition from nucleate boiling (i.e. boiling in its usual sense) to film boiling, where the heater is covered by a continuous vapour film. The BC is observed when the heat flux from the heater exceeds a critical value. Heat exchange then falls down and endangers the exchanger whose temperature rises abruptly. The physical mechanism of the BC is still under debate. We propose the recoil force (the thrust of vapour production) at the solid–liquid–vapour contact line to lie at the origin of the BC. At large heat flux, the recoil force tends to spread the vapour bubble that otherwise would not wet the solid. We give both analytical and numerical analysis in support of this idea. We also report experiments under microgravity conditions performed with near-critical fluids (SF6 and CO2). The absence of gravity effects and the vicinity of the critical point where the liquid–vapour surface tension vanishes emphasize the influence of the recoil force: during heating, the vapour drop is indeed seen to spread. | |
