Forced Convection with Counterflow in a Circular Tube Occupied by a Porous Medium

D A Nield
University of Auckland Auckland, New Zealand

RÉSUMÉ

An analytical solution is obtained for forced convection with counterflow in the core and sheath of a circular tube occupied by a saturated porous medium. The Brinkman model is employed for the porous medium. It is found that the effect of counterflow (in contrast to flow in one direction) is to reduce the value of the Nusselt number for large values of the core-sheath coordinate ξ, but to increase it for small values of ξ. In particular, Nu takes a zero minimum value when the mean velocity is zero.
