Abstract
The problenr of' the fiee convectioll t'rom a vertical heated plate embedded in a
porous mediunr is investigated nurnericall-v in the prese,it paper. The plate
telnperuttlle is assurrted to lrave e.xponential variation along rhe plate. The goveming.
equations are simplified using the nvo-dirnensional transient lamirrbr boundarv lar.ei
theor-v- togetlter with the Boussinesq and Darcl approxirnations. The full1.' inrplicit
finite volurne ntethod is used rvith the porver larv schenre to solve the non- ' dimensional system of equations. The 'e.\ponentially nutnerical results are preserlted for isotlermal,
increasing and exponehtially decreasing plate temperatur.es. It is fbund

incleasing the plate tetnperature leads to increase in the transient and the steadv slate
