TL;DR: In this article, the authors investigated the dispersion process in an oscillatory flow of a layered liquid, where the center region is the Casson liquid surrounded by a Newtonian liquid layer flowing through a narrow pipe under the wall reaction.

TL;DR: In this paper, the authors considered the impact of heterogeneous (kinetic reversible phase exchange and irreversible absorption) chemical reactions along with a homogeneous first-order reaction for the dispersion of a solute in a solvent flowing through an annular pipe under a periodic pressure gradient.

TL;DR: An analysis of the solute dispersion in the liquid flowing through a pipe by means of Aris-Barton's "method of moments" under the joint effect of some finite yield stress and irreversible absorption into the wall is presented in this paper.

TL;DR: In this article, a finite difference implicit scheme has been adopted to solve the Aris integral moment equations arising from the unsteady convective diffusion equation for all time periods, and the axial distributions of mean concentration are approximated using Hermite polynomial representation from the first four central moments for a range of different reaction-rate parameters.

TL;DR: In this paper, the authors investigated Taylor dispersion of reactive species in Casson liquid in an oscillatory flow because of the pulsatile pressure gradient and found that both wall absorption and bulk flow reaction have a significant response on dispersion phenomena.
