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.
The mechanisms of the formation of vapor bubbles of a critical size in deformable droplets of the dispersed phase in liquid emulsion been studied. The model is proposed breakup of the droplets in gradient flow of the emulsion near the surface heating under the combined action of viscous shear stresses and thermal overload. Was the dependence of the heat flux density at boiling of dispersed drops of low-temperature liquid phase in a gradient flow of the emulsion near hard surface. Comparison with the data of experimental studies shows the validity of the proposed model concepts that are different from the usual boiling of homogeneous fluids at surface heating.
Specification of model representations of complex transfer processes in liquid emulsions based on mechanisms of the basic physical phenomena (MВPP) is considered in this paper. For the representation of the complex models of the transfer processes in a generalized form a correspondence of dimensionless similarity criteria and the most simple, basic physical phenomena are used. With a lack of complete mathematical models they are replaced by a set of such basic phenomena which express physical content of a complex process. Regressive relationships between the corresponding similarity criteria are evaluated on the basis of the experimental measurement data. As a result, a formal statistical analysis is filled with an objective physical content in accordance with the nature of the MВPP.
