Nonlinear Convective Flow of Magnetohydrodynamic Oldroyd 8-Constant Fluid in a Channel With Chemical Reaction and Convective Boundary Condition

Abstract

The present work concentrates on the two-dimensional steady incompressible flow of an Oldroyd-8 constant fluid between vertical plates influenced by a magnetic field. The cross diffusive and second-order chemical reactions are incorporated into the study. The homotopy analysis method (HAM) is used to obtain the series solutions of the transformed system of nonlinear equations. The effects of these parameters on the dimensionless velocity, temperature, concentration, skin friction, and Nusselt and Sherwood numbers are also investigated for various values of relevant parameters affecting the flow and heat transfer phenomena. The most relevant outcomes of the present study are that enhancement in magnetic field strength undermines the flow velocity, temperature, and concentration establishing thinner related boundary layer. Another important outcome is that an increase in the Dufour parameter upsurges the rate of heat transfer at the wall y = 0 while peters out at y = 1. Finally, the second-order chemical reaction parameter reduces the concentration distribution. The novel outcomes of this investigation will be helpful in the field of the aerosol technology.

Thermal performance of Ag–water nanofluid flow over a curved surface due to chemical reaction using Buongiorno's model

“…The authors have molded the nanofluid flow past a stretching curved surface in the presence of chemical reaction, Brownian motion, and thermophoresis. The dimensionless set of flow Equations (19) to (21) along with assisted boundary conditions (22) is solved numerically implementing shooting scheme using RKF45 order technique. The description of RKF45 technique is based on a study by Mishra et al, 27 Mishra and Kumar, 39 and Makinde et al 43 The numerical process is confirmed by doing a comparison with previous findings for θ − ′(0) with different values of Pr.…”

“…Generally, RKF45 order technique is used to solve initial value problems (IVPs), thus Equations (19) to (21) are converted to first order. For the present scheme, these equations can be reorganized as…”

“…Pal and Mondal 18 inspected combined influences of chemical reaction and radiation of a convective fluid flow in the direction of a stretched field with saturated porous media. Yusuf et al 19 observed the performance of chemically reactive MHD flow of Oldroyd B‐constant fluid using a channel subjected to convective limit conditions. They showed that acceleration in chemical reaction parameter decreases concentration distribution.…”

Nonlinear convection flow of dissipative Casson nanofluid through an inclined annular microchannel with a porous medium

“…They discovered that a hike in both linear and nonlinear convective parameters enhanced the velocity and temperature profiles but depleted the energy of the system. The MHD Oldroyd 8‐constant fluid flow between vertical plates with chemical reaction was examined by Yusuf et al, 25 who revealed that enhancement in magnetic field strength undermines the flow velocity, temperature, and concentration. The flow of a hyperbolic tangent fluid with the Cattaneo–Christov heat and mass diffusion through a stretching surface was reported by Ibrahim and Gizewu 26 .…”
