Mathematical description of the dissolution prosess
in ideal-mixing apparatus
S.P. Fedorov, Yu.V. Sharikov, V.D. Lunev
The general approach to solving problem about kinetics of a mass-transfer of polydispersed
systems with an environment with reference to processes of dissolution in ideal-mixing apparatus is advanced. For this
variety of phase transition in systems of a polydispersed structure a number of rather simple relations circumscribing
evolution in time a frequency function of particle-size distribution, mass of a solid phase and density of solution
suitable for practical usage in the chemical technology, is obtained. The equation for peripheral speed of dissolution
of a single particle in different hydrodynamic conditions is analyzed. The equation for frequency of "disappearance"
of particles at dissolution of a polydispersed system, which one is to straight lines analog (to be exact by antipode)
nucleation during a mass crystallization is adduced.
The considered approach can be widespread on processes of liquid drops (mists) evaporation
and combustion of polydispersed fuels.
