Formation and stability of a liquid microlayer in pool boiling and growth of a dry area

Abstract

The physical processes occurring in the evaporating liquid microlayer between a solid surface and a growing vapour bubble have been investigated theore 1. (i) The mechanism of microlayer formation is described by a balance of surface tension and deceleration force, in contrast to the usual boundary layer 2. (ii) For the formation of a dry area the “roll-up” (“slip”) effect caused by surface tension and contact angle is included, in contrast to prev where only evaporation is accounted for. The results agree with the sparse experimental results available in literature and they explain discrepancies between theory and experiment found by ot
