Abstract

This paper considers the unsteady laminar free convection produced by heating an infinite vertical flat plate. Analytical solutions in closed forms for the velocity and temperature profiles, when the surface temperature varies stepwise and as a power of time, are obtained for Prandtl numbers close to unity.Results are reported for several values of the Prandtl number in case of a stepwise varying plate temperature.
