Abstract

An exact solution is presented to investigate the effects of viscous dissipation on the thermal development of a liquid-metal fluid flowing in a circular tube with a uniform wall temperature filled by a saturated porous medium. The Hazen-Dupuit-Darcy model is employed. The analysis leads to expressions for the local Nusselt number, as a function of the dimensionless axial coordinate Peclet and Brinkman numbers.
