(in lingua inglese)
A mathematical model was presented for hydromagnetic threedimensional Couette flow of a viscous, incompressible, electrically-conducting and chemically-reacting fluid between two vertical flat porous plates with a transverse sinusoidal injection of the fluid at the stationary plate and its corresponding removal by constant suction through the plate in uniform motion, with a chemical reaction first order. The governing non-linear coupled partial differential equations were solved by an implicit finite difference scheme of Gauss–Seidel iteration technique and representative set of results were obtained to illustrate the details of flow characteristics and their dependence on some of the physical parameters.
