Zusammenfassung
Forced convection in a plane channel filled with a saturated bi-disperse
porous medium, coupled with conduction in plane slabs bounding the
channel, is investigated analytically on the basis of a two-velocity,
two-temperature model. It is found that the effect of the finite
thermal resistance due to the slabs is to reduce both the heat transfer
to the porous medium and the degree of local thermal non-equilibrium.
An increase in value of the P�clet number leads to a decrease in
the rate of exponential decay in the downstream direction but does
not affect the value of a suitably defined Nusselt number. The dependence
of Nusselt number on Biot number associated with the boundary slabs,
the interphase heat exchange parameter, the interphase thermal conductivity
ratio, the interphase effective permeability ratio, and the macroscopic
void fraction, is investigated.
