Effects of chemical reactions on MHD micropolar fluid flow past a vertical plate in slip-flow regime

Abstract

Heat and mass transfer effects on the unsteady flow of a micropolar fluid through a porous medium bounded by a semi-infinite vertical plate in a slip-flow regime are studied taking into account a homogeneous chemical reaction of the first order. A uniform magnetic field acts perpendicular to the porous surface absorb micropolar fluid with a suction velocity varying with time. The free stream velocity follows an exponentially increasing or decreasing small perturbation law. Using the approximate method, the expressions for the velocity microrotation, temperature, and concentration are obtained. Futher, the results of the skin friction coefficient, the couple stress coefficient, and the rate of heat and mass transfer at the wall are presented with various values of fluid properties and flow conditions.

Chemical Reaction and Thermal Diffusion Effects on Mass Transfer Flow through an Inclined Plate

“…It can be designated as either a mixed or stable process, which be contingent on whether it occurs at a boundary or as a single-phase volume reaction. Chaudhary and Jha [12] studied the effect of chemical reaction on MHD micropolar fluid flow past a vertical plate in slip flow regime. Effects of mass transfer with a chemical reaction on unsteady flow past an accelerated isothermal vertical plate are investigated by Muthuchumaraswamy et al [13].…”

Dual solutions for radiative MHD forced convective flow of a nanofluid over a slendering stretching sheet in porous medium

“…Ibrahim et al (2013) discussed the MHD boundary layer flow of a nano fluid past a permeable stretching with velocity and thermal slip boundary conditions. Chaudhary and Jha (2008) studied the influence of chemical reaction on MHD micro polar fluid flow over a vertical plate in slip-flow regime. The effects of thermal radiation and chemical reaction on MHD convective flow over a permeable stretching surface with suction and heat generation was studied by Mohankrishna et al (2015).…”

Heat and Mass Transfer on MHD Fluid Flow Over a Semi Infinite Flat Plate With Radiation Absorption, Heat Source and Diffusion Thermo Effect

“…The study of chemical reaction with heat transfer in porous medium has important engineering applications e.g., tabular reactors, oxidation of solid materials and synthesis of ceramic materials. Heat and mass transfer effects on the unsteady flow of a micropolar fluid through a porous medium bounded by a semi-infinite vertical plate in a slip-flow regime are studied taking into account a homogeneous chemical reaction of the first order numerically studied by Chaudhary and Jha (2008). Patil and Chamkha (2013) Soundalgekar and Wavre (1997) exhibited all effects on unsteady free convection flow past an infinite plate.…”
