Abstract :
In this work, a numerical study of forced convection of an incompressible fluid through a cylinder filled with
a porous medium is carried out by taking into account the heat due to viscous dissipation. Dimensionless
equations of the problem are solved numerically. The energy transport bidimensional model is based on the
local non-thermal equilibrium assumption with consideration of viscous dissipation effects. The influence of
various parameters like Darcy number, Reynolds number, Forchhheimer coefficient and Eckert number on
temperature fields is investigated and examined throughout this paper. It is found that all these parameters
have significant influence on thermal performance of the packed bed within certain conditions.
