The Asymptotic Solution for the Steady Variable-Viscosity Free Convection Flow on a Porous Plate

Abstract

Under an arbitrary time-dependent heating of an infinite vertical plate (or wall), the steady viscosity-dependent free convection flow of a viscous incompressible fluid is investigated. Using the asymptotic method of solution on the governing equations of motion and energy, the resulting Ordinary differential equations were solved numerically. And the results show that the fluid energy decreases as the distance moved by the plate increases.
