Dual solutions for unsteady mixed convection flow of MHD micropolar fluid over a stretching/shrinking sheet with non-uniform heat source/sink

Abstract

a b s t r a c tThe aim of the present study is to investigate the influence of non-uniform heat source/sink, mass transfer and chemical reaction on an unsteady mixed convection boundary layer flow of a magnetomicropolar fluid past a stretching/shrinking sheet in the presence of viscous dissipation and suction/ injection. The governing equations of the flow, heat and mass transfer are transformed into system of nonlinear ordinary differential equations by using similarity transformation and then solved numerically using Shooting technique with Matlab Package. The influence of non-dimensional governing parameters on velocity, microrotation, temperature and concentration profiles are discussed and presented with the help of their graphical representations. Also, friction factor, heat and mass transfer rates have been computed and presented through tables. Under some special conditions, present results are compared with the existed results to check the accuracy and validity of the present study. An excellent agreement is observed with the existed results.

Physical aspects on unsteady MHD‐free convective stagnation point flow of micropolar fluid over a stretching surface

“…Micropolar fluid flow induced by a stretchable surface was reported by Chiam . Simultaneous solutions for the time‐dependent mixed convective flow of micropolar fluid across a shrinking surface with heat and mass transfer attributes were reported by Sandeep and Sulochana . A numerical exploration of the boundary layer flow of non‐Newtonian fluid across a stretched surface with Lorentz force can be viewed in Ramachandran et al Turkyilmazoglu examined in a study, the two‐dimensional (2D) flow of an incompressible magnetohydrodynamic dusty fluid across a shrinking/stretching sheet in the presence of a porous medium and presented an analytical solution.…”

“…Lukaszewicz used lubrication theory to report the mathematical equations for micropolar fluids field. Sandeep and Sulochana claimed that dual solution can exist regarding the flow of micropolar fluid along with the impact of heat absorption and generation effects. The consequences of micropolar fluid flow over the stretched sheet with homogenous injection/suction phenomenon have interpreted by Abo‐Eldahab and El‐Aziz .…”

Numerical Investigation of Heat and Mass Transfer in Radiative Magnetohydrodynamic Flow with Chemical Reaction

“…The influence of viscous dissipation on MHD boundary layer flow and heat transfer of a dusty fluid in a porous medium over an exponentially stretching sheet was experimented by Pavithra and Gireesha [22]. The influence of nonuniform heat source, mass exchange and chemical reaction on an precarious blended convection boundary layer flow of a magnetic fluid past a stretching sheet in the presence of viscous dissipation have be depicted by Sandeep and Sulochana [23]. The magnetohydrodynamic boundary layer flow and heat transfer of an incompressible, viscous and electrically conducting fluid, the flow is considered over a stretching sheet in the presence of transverse magnetic field with heat source/sink was analyzed by Pantokratoras [24].…”
