Effects of Aligned Magnetic Field and First Order Chemical Reaction on an Unsteady Convective Heat and Mass Transfer Flow past a Vertical Plate Embedded in a Porous Medium

This paper investigates the combined effects of aligned magnetic field and first order chemical reaction on unsteady convective heat and mass transfer flow past a vertical plate embedded in a porous medium is presented. At time t′; >0, the plate starts moving in its own plane with an impulsive velocity in the vertical upward direction against the gravitational field and at the same time, the plate temperature and concentration levels near the plate raised linearly with time t′. A transverse magnetic field of uniform strength B₀ is assumed to be applied at an angle α with the fluid flow direction. The resulting dimensionless coupled linear partial differential equations are solved by using Laplace transform technique. Effects of various flow parameters entering into the problem on flow quantities are discussed andanalyzed through graphs and tables.
