Description
Summary:This article concentrates on the properties of three-dimensional magneto-hydrodynamic flow of a viscous fluid saturated with Darcy porous medium deformed by a nonlinear variable thickened surface. Analysis of flow is disclosed in the neighborhood of stagnation point. Features of heat transport are characterized with Newtonian heating and variable thermal conductivity. Mass transport is carried out with first order chemical reaction and variable mass diffusivity. Resulting governing equations are transformed by implementation of appropriate transformations. Analytical convergent series solutions are computed via homotopic technique. Physical aspects of numerous parameters are discussed through graphical data. Drag force coefficient, Sherwood and Nusselt numbers are illustrated through graphs corresponding to various pertinent parameters. Graphical discussion reveals that conjugate and constructive chemical reaction parameters enhance the temperature and concentration distributions, respectively.
