Magneto hydrodynamic Fluid Flow past Contracting Surface Taking Account of Hall Current

Abstract

An unsteady, laminar hydrodynamic flow of an incompressible, viscous and electrically conducting Newtonian fluid over a porous contracting sheet in a rotating system considering hall current effects and heat source has been studied. The governing system of partial differential equations is transformed to dimensionless equations. The dimensionless equations are then solved numerically using the finite difference method. Using graphs the effects of various parameters on velocity, temperature and concentration are discussed The results obtained here are useful in applications on wire and glass fiber drawing in cooling of nuclear reactors, cooling of metallic plates and metallurgy.
