Transient convective mass transfer for a fluid sphere dissolution in an alternating electric field

Mass Transfer during Solute Extraction from a Droplet with Internal Circulation in the Presence of a Constant Uniform Electric Field

“…It follows from Eq. (23) that, for a binary system, the solution of a continuous-phase controlled mass transfer problem has the following form (see also [4]):…”

“…Morrison [3] found that the heat and mass transfer rates were proportional to the magnitude of the applied electric field for both transient and steady heat and mass transfer. In previous studies, e.g., [3,4], mass transfer during droplet dissolution under the influence of an electric field was investigated for a continuous phase controlled mass transfer case, but in the present study the resistance to mass transfer, in both the dispersed and continuous phases, is taken into account. This approach accounts for a change of the solute concentration in the bulk of the dispersed phase, and the analysis of mass transfer during extraction is reduced to a numerical solution of the Volterra integral equation of the second kind.…”

“…b-Chitin is interesting because of some specific properties, including high solubility and swelling due to much weaker intermolecular hydrogen bonding ascribable to the parallel arrangement of the main chains. Thus, b-chitin may be anticipated to exhibit better solubility properties in a variety of solvents and a higher reactivity than a-chitin [3], it also shows better reactivity than a-chitin during deacetylation [4].…”

Non-linear mass transfer from a solid spherical particle dissolving in a viscous fluid

“…The comprehensive review can be found in [2]. In recent papers [3,4] the effect of finite dilution on the mass transfer between a flow and a single inclusion was studied keeping the assumption of a constant density of the mixture. This approach proved to be very effective since it allows the use a known velocity field and it obviously provides a leading order approximation for a solution in the case when the intensity of the flow induced by the mass transfer is small compared to that of an externally imposed flow.…”
