TL;DR: In this article, the hydraulic radius model was applied to laminar flow in a packed bed and assuming that mass transfer in the packed bed is analogous to that between a pipe surface and a stream of liquid with steady velocity profile, liquid-phase mass transfer from the packed solid sphere was analyzed and an approximate solution was proposed.

TL;DR: In this article, a diaphragm-type liquid membrane impregnated with Amberlite LA-II as a mobile carrier was used to obtain fundamental information for developing liquid membrane process.

TL;DR: In this article, the authors measured the permeation rate of copper with a liquid membrane process and found that it is explained by diffusional process in the membrane for a chelating complex between copper and carrier and by the succeeding stripping reaction at the interface between the membrane and stripping phase.

TL;DR: In this paper, a stream function for laminar flow around a single drop moving in a viscous fluid is numerically solved in the low Reynolds number region by use of Galerkin's method in a way similar to that of Hamielec et al.
