چکیده انگلیسی


• Non-Newtonian fluid flow is a model problem in petroleum engineering in processes.
• We investigate the parameter dependence of flow quantities in a typical such flow.
• We observe transient increase in velocity (W) & transient decrease in concentration (ϕ).
• In steady state, W and ϕ both increase or both decrease together.
• Parameters that increase/decrease the source terms would increase/decrease both W & ϕ.

This article examines the unsteady, pressure driven flow of a non-Newtonian fluid with reacting species in a parallel plate channel filled with a homogeneous, isotropic and saturated porous medium. A differential type third grade constitute equation is employed to model the non-Newtonian character of the fluid. The coupled nonlinear partial differential equations governing the problem are derived and solved numerically using a semi-implicit finite difference scheme. Graphical results are presented and discussed qualitatively and quantitatively with respect to various parameters embedded in the problem.
