Comparison of the calculated dependencies obtained for boiling emulsion with low-boiling dispersed phase based on the model of Labuntsov [1] for an advanced boiling homogeneous liquid at the solid wall, have been compared with the experimental data presented in [3]. The obtained model curve was in good agreement with measurements of heat flux in boiling water emulsion is heated platinum wire. It has been determined, that all the experimental points are grouped around two curves with different model constants that can be interpreted as the presence of two modes the nucleate boiling.

“…Results of the analysis of the conditions of stable nucleation in the low-boiling disperse phase taking into account the turbulent mode of motion of liquid emulsions presented [4]. Proposed calculated relation for estimating the dependence of the minimum size of drops, whose boiling up can initiated by the resonance mechanism of their destruction by turbulent pulsations on the superheating temperature.…”

The growth of bubbles to the critical size, resulting in a volume of superheated droplets, which dispersed in high-boiling continuous medium liquid emulsion. Based on the first law of thermodynamics analysis of the formation of a new liquid-vapor interface surface and the nature of the phase transitions of the first kind in the closed medium, which is limited to the surface of the droplets of the dispersed phase. Shows the presence of factors associated with the size of the bubbles of vapor with a constant supply of heat through the interface. Presents the dependencies that fundamentally different from those describe boiling in unlimited volume fluid or near the surface of the heated wall.
