Abstract

Aim of the paper is to investigate the effect of linear thermal stratification in stable stationary ambient fluid on steady convective flow of a viscous incompressible electrically conducting fluid along a moving, non-isothermal vertical plate in the presence of transverse magnetic field. The governing equations of continuity, momentum and energy are transformed into ordinary differential equations using local similarity transformation. The resulting coupled non-linear ordinary differential equations are solved using Runge-Kutta fourth order method along with shooting technique. The velocity and temperature distributions are discussed numerically and presented through graphs. The numerical values of skin-friction coefficient and Nusselt number at the plate are derived, discussed numerically for various values of physical parameters and presented through Tables.
