Abstract:

This article presents the heat and mass transfer characteristics of unsteady MHD flow of a viscous, incompressible and electrically conducting micropolar fluid in the presence of viscous dissipation and radiation over a porous stretching sheet with chemical reaction. The governing partial differential equations (PDEs) are reduced to ordinary differential equations (ODEs) by applying suitable similarity transformations which are then solved numerically using fourth order Runge-Kutta method. The results are depicted graphically for velocity, angular velocity, temperature and concentration profiles for various values of parameters such as unsteadiness parameter, magnetic parameter, porous parameter, thermal Grashof number, solutal Grashof number, Prandtl number, thermal radiation parameter, Eckert number, Schmidt number and chemical reaction parameter. To check the accuracy of our numerical code, comparison is made with the existing results. The influence of various parameters on skin friction coefficient, couple stress and rates of heat and mass transfer coefficients are presented numerically in tabular form.

MHD Three-Dimensional Stagnation-Point Flow and Heat Transfer of a Nanofluid over a Stretching Sheet

In this study, the three-dimensional magnetohydrodynamic (MHD) boundary layer of stagnation-point flow in a nanofluid was investigated. The Navier–Stokes equations were reduced to a set of nonlinear ordinary differential equations using a similarity transform. The similarity equations were solved for three types of nanoparticles: copper, alumina and titania with water as the base fluid, to inve...

Heat Transfer on Mhd Viscous Flow over a Stretching Sheet with Prescribed Heat Flux

A steady three-dimensional Magnetohydrodynamic (MHD) boundary layer viscous flow and heat transfer due to a permeable stretching sheet with prescribed surface heat flux is studied in presence of a uniform applied magnetic field transverse to the flow. Using the implicit finite-difference scheme, known as the Keller-box method, the nonlinear ordinary differential equations are solved. The veloci...
