Deterioration of Heat Transfer in Boiling of Emulsions with a Low-Boiling Disperse Phase

详细

The paper presents the results of an experimental study of heat transfer in the boiling of emulsions consisting of water dispersed in organosilicon fluids, namely, in PMS-20 or PES-4 silicon oil. The evaporation process during boiling was studied with a high-speed filming technique. It is demonstrated that the transition from boiling of the emulsion disperse phase to simultaneous boiling with the dispersion medium is accompanied by deterioration in heat transfer due to the disperse phase nucleate boiling crisis.
