Abstract

The numerical study of a diffusion flame over a porous flat plate showed that the observed velocity overshoot around the flame region is primarily due to the pressure gradients induced because of the confined nature of the flow. The phenomenon of combustion by itself is unlikely to induce significant pressure nonuniformities which can describe the observed levels of overshoot in velocity. The buoyancy effects can, however, induce velocity overshoot to a certain extent. The exact prediction of the velocity and temp. profiles calls for inclusion of buoyancy effects, a more accurate estn. of injection velocity, and a better description of transport property variation in addition to the pressure gradients induced by the confined nature of the flow.
