“…The value of diffusivity is determined by comparing the experimental results with the theoretical expression for the mass flux to a cone. The existing theoretical correlations for the rate of mass transfer between a stagnant and rotating cone and a non-Newtonian fluid flow (see, e.g., [1,2]) were derived in the approximation of the infinite dilution of the solute in a solvent and for the case with isothermal dissolution. The goal of the present investigation is to determine correlations for heat and mass transfer during cone dissolution in a non-Newtonian fluid which are valid for a case of finite concentration levels of a solute in a solvent and for nonisothermal dissolution.…”

Coupled mass and heat transfer between a cone and a non-Newtonian fluid was studied when the concentration level of the solute in the solvent is finite (finite dilution of solute approximation). Convective heat and mass transfer between a laminar flow and a stationary cone and between a rotating cone and a quiescent fluid is investigated. Solutions of both problems are found in the form of the dependencies of Sherwood number vs. Reynolds and Schmidt numbers. Coupled thermal effects during dissolution and solute concentration level effect on the rate of mass transfer are investigated. It is found that the rate of mass transfer between a cone and a non-Newtonian fluid increases with the increase of the solute concentration level. The suggested approach is valid for high Peclet and Schmidt numbers. Isothermal and nonisothermal cases of dissolution are considered whereby the latter is described by the coupled equations of mass and heat transfer. It is shown that for positive dimensionless heat of dissolution, K > 0, thermal effects cause the increase of the mass transfer rate in comparison with the isothermal case. On the contrary, for K < 0 thermal effects cause the decrease of the mass transfer rate in comparison with the isothermal case. The latter effect becomes more pronounced with the increase of the concentration level of the solute in a solvent.
