External and internal problems of modeling the heat and mass transfer coefficients at particles motion in liquids

An approach to the determination of the heat and mass transfer coefficients from dispersed particles by the development of the hydrodynamic analogy is considered. The equations for computing the heat and mass transfer coefficients in continuous phase at a laminar regime of the flow around solid particles as well as the mass transfer coefficients in droplets are obtained. Comparisons with the experimental data of different authors are presented.
