This article discusses the effect of heat and mass transfer in a boundary layer flow in the presence of a magnetic field of an electrically conducting and viscous fluid as it passes through a porous medium containing a heat source and a chemical reaction. By employing similarity variables, the governing equations are changed into nonlinear ordinary differential equations(ODEs). To solve the obtained...
This paper focuses on the theoretical analysis of blood flow in the presence of thermal radiation and chemical reaction under the influence of time dependent magnetic field intensity. Unsteady non linear partial differential equations of blood flow consider time dependent stretching velocity, the energy equation also accounts time dependent temperature of vessel wall and the concentration equation...
The present analysis is focused on the study of the magnetic effect on coupled heat and mass transfer by mixed convection boundary layer flow over a slender cylinder in the presence of a chemical reaction. The buoyancy effect due to thermal diffusion and species diffusion is investigated. Employing suitable similarity transformations, the governing equations are transformed into a system of coupled...
An exact analysis of rotation effects on an unsteady flow of an incompressible and electrically conducting fluid past a uniformly accelerated infinite isothermal vertical plate, under the action of a transversely applied magnetic field is presented.

An exact solution of an unsteady flow past an exponentially accelerated infinite isothermal vertical plate with uniform mass diffusion in the presence of a transverse magnetic field has been studied. The plate temperature is raised to Tw and the species concentration level near the plate is also made to rise Cʹw . The dimensionless governing equations are solved using the Laplace-transform technique...
Thermal radiation and hydromagnetic effects on an unsteady free convective flow of a viscous incompressible flow past an infinite vertical oscillating plate with variable temperature and mass diffusion are presented, taking into account the homogeneous chemical reaction of first order. The fluid considered here is a gray, absorbing-emitting radiation but a non-scattering medium. The plate temperature...
A finite difference solution of MHD and thermal radiation effects on unsteady flow past an impulsively started semi-infinite vertical plate in the presence of homogeneous chemical reaction of first order have been studied. The dimensionless governing equations are solved by an efficient, more accurate, unconditionally stable and fast converging implicit finite difference scheme. The effects of velocity...
An analysis is carried out to study a nonlinear hydromagnetic flow, heat and mass transfer over an accelerating vertical surface with internal heat generation and chemical reaction. The fluid is assumed to be incompressible, viscous, electrically conducting and Boussinesq. A magnetic field is applied transversely to the direction of the flow. The similarity transformation has been utilized to convert...
