Abstract
The unsteady heat transfer process involved in free convection flow al ong a vertical surface embedded in a porous medium is investigated. An analytical solution has been obtained for the temperature/velocity fi eld for small times in which the transport effects are confined within an inner layer adjacent to the plate. Then, a numerical solution of t he full boundary-layer equation is obtained for the whole transient fr om the initial unsteady state to the final steady state. Detailed resu lts of the effect of the temperature inputs on the transient process a re given. (C) 1997 Elsevier Science Ltd.
