Mass-transfer of a polydispersed system of dissolved particles with an environment
theoretically is investigated if there is sources of a disperse phase uniformly distributed on a reactionary volume.
Non-linear, as a whole, the problem is adduced to convenient for calculations form. The frequency of disappearance of
particles is retrieved at dissolution as a function of time. The stochastic characteristics of distribution of
particles on time of dissolution with allowance for their disappearances and general non-linearity of a problem
are determined. The expression for mean on an ensemble of time of dissolution is obtained.
The offered theory is possible is to distributed to processes of vaporization of mists and other drops of a
liquid of a polydispersed structure suspended in atmosphere of incompletely saturated vapour and also combustion
of polydispersed fuels.
The obtained outcomes can be used for mathematical modeling and calculation of a kinetics of dissolution,
vaporization and combustion of polydispersed systems.
Practicable fields of application: the chemical technology, meteorology, power engineering etc.
Explicitly this theory is considered in //ДАН (Reports of Academy of sciences USSR), 1990, V. 312, № 2,
p. 386 - 390.
