N. K. Gupta, U. S. Rajput

Abstract


In this paper, we are analyzing Soret effect and inclined magnetic field on unsteady free
convection MHD flow past an impulsively started vertical plate with chemical reaction. Fluid
considered is electrically conducting. The Laplace transform method has been used to find
the exact solutions for the concentration, momentum and energy equations. The flow model
consists of a magnetic field inclined from vertical by an angle . The flow is considered
unsteady and heat is transferred through free convection. The velocity profiles are discussed
with the help of graphs drawn for different parameters like thermal Grashof number, the
Soret number, the Prandtl number, the chemical reaction parameter, the Hartmann number,
the Schmidt number, the mass Grashof number, time and inclination of magnetic field. The
numerical values of skin friction have been discussed with the help of table for different
parameters.

Keywords
