Summary
Exact solutions of the Navier-Stokes equations and the energy equation neglecting dissipation terms for natural convection from a porous vertical flat plate have been obtained in the following two cases: (i) when the plate is suddenly raised to a uniform higher temperature, (ii) when the plate suddenly begins to generate a uniform heat flux at its surface. Expressions for the skin friction and coefficient of heat transfer at the plate have been obtained. Skin friction decreases with suction in both cases.
