TLDR
In this paper, the authors extended the Graetz problem in heat transfer to the analysis of mass transfer in circular ducts for the cases where wall resistance is included and where non-Newtonian fluids that obey Casson's equation are considered.
Abstract
The Graetz problem in heat transfer is extended to the analysis of mass transfer in circular ducts for the cases where wall resistance is included and where non-Newtonian fluids that obey Casson's equation are considered. The eigenvalues and fluid bulk coefficients are presented for the fluid between the extremes of Newtonian and slug flow. It is found that for fluids which are only slightly non-Newtonian, such as blood, which is closely approximated by Casson's equation, the mass transfer rate can be predicted by Newtonian fluid analysis without appreciable error. Some experimental results give support to the theory.

Fine particle deposition in laminar flow through parallel-plate and cylindrical channels

TL;DR: In this article, the authors considered the deposition of colloidal particles from a suspension in steady fully developed laminar flow onto the walls of a channel is rationalized as equivalent to mass transfer in the bulk with a first-order reaction at the walls.

Extraction of Cr(VI) with aliquat 336 in hollow fiber contactors: mass transfer analysis and modeling

TL;DR: In this paper, the mass transfer analysis and modeling of the hollow fiber non-dispersive liquid extraction of Cr(VI) with Aliquat 336 is reported, and the integration of the mass conservation equation with a nonlinear equilibrium condition at the fiber wall with all the experimental results, using as criterion the minimum weighted standard deviation, gave as a result the value of the parameter D = 2.3 × 10−9 m2/s and values of Keq dependent upon the initial concentration of the feed solution.

Polymeric Hollow Fiber Heat Exchangers: An Alternative for Lower Temperature Applications

TL;DR: In this paper, plastic heat exchangers are of increasing interest for lower temperature applications, because of their better chemical resistance and fouling characteristics, and their lower thermal performance is more suitable for low temperature applications.
