Boundary layer flow of a nanofluid in an inclined wavy wall with convective boundary condition

Abstract

This problem focuses on the laminar flow of a nanofluid in an inclined permeable parallel walls. We assume that the lower wall is wavy while the upper wall is flat with Dufour effects, Soret effects, and a magnetic field effect with boundary conditions been convective. The rectangular coordinate system has been used to present the model for this problem. It also incorporates the effect of thermophoresis parameter and Brownian motion. The obtained similarity solution is dependent on the thermophoresis number (Nt ), Darcy number (Da), Magnetic parameter (M), Dufour (DU) number, Soret (Sr) number, Brownian motion (Nb), Lewis number (Le), Prandtl number (Pr). It is found that at the wavy wall, the fluid flow back.
