INCLINED WALL PLUMES IN POROUS-MEDIA

We present a numerical solution of the natural convection from incline d wall plumes which arise from a line thermal source imbedded at the l eading edge of an adiabatic plate with arbitrary tilt angle between 0 and pi/2, and embedded in a fluid-saturated porous medium. An appropri ate transformation of the governing boundary-layer equations is propos ed and a very efficient novel numerical solution is proposed to obtain rigorous numerical solutions of the transformed nonsimilar equations over a wide range of tilt angle from the vertical to the horizontal. G raphs are presented showing the effect of the tilt angle on the veloci ty and temperature profiles, as well as on the wall velocity and wall temperature. As far as we know, this problem has not yet been studied in the available literature.
