The Unsteady Variable – Viscosity Free Convection Flow on a Porous Plate

Abstract

The unsteady variable-viscosity free convection flow of a viscous incompressible fluid near an infinite vertical plate (or wall) is investigated under an arbitrary timedependent heating of the plates, and the governing equations of motion and energy transformed into ordinary differential equations. Employing asymptotic techniques, the resulting equations are solved numerically. It is shown that the velocity decreases as the ratio of the kinematic viscosity to the initial temperature increases.
