Da. Nield et al., FORCED-CONVECTION IN A FLUID-SATURATED POROUS-MEDIUM CHANNEL WITH ISOTHERMAL OR ISOFLUX BOUNDARIES, Journal of Fluid Mechanics, 322, 1996, pp. 201-214
We present a fresh theoretical analysis of fully developed forced conv
ection in a fluid-saturated porous-medium channel bounded by parallel
plates, with imposed uniform heat flux or isothermal condition at the
plates. As a preliminary step, we obtain an 'exact' solution of the Br
inkman-Forchheimer extension of Darcy's momentum equation for flow in
the channel. This uniformly valid solution permits a unified treatment
of forced convection heat transfer, provides the means for a deeper e
xplanation of the physical phenomena, and also leads to results which
are valid for highly porous materials of current practical importance.
