Diffusive Species in MHD Squeezed Fluid Flow Through non-Darcy Porous Medium with Viscous Dissipation and Joule Heating

Abstract

This article focuses the flow through non-Darcy porous medium. The flow is due to the squeezing phenomenon. The magneto viscous fluid is accounted. Formulation of the flow problem is interpreted the salient features of Ohmic heating (Joule heating), viscous dissipation and auto-catalyst and reactants (i.e. homogeneousheterogeneous reactions). A whole analysis is carried out with different diffusion coefficients for both auto-catalyst and reactants. It is also desired to observe the dependence of convective surface condition on flow regime in heat transport process. The resulting non-linear partial differential equations are found to be governing by dimensionless ordinary differential equations with the implementation of similarity solutions. A homotopic procedure based on an iterative scheme is utilized for the solutions of the flow problem. Flow velocity, fluid temperature and concentration are addressed via graphs for different values of geometrical and rheological parameters of considered flow problem. Moreover, skin friction co-efficient and Nusselt number are sketched and discussed graphically. The analysis reveals that higher values of mass diffusion ratio parameter result reduction in concentration of specie B whereas concentration of specie A enhances for higher mass diffusion ratio parameter.
