Abstract
This study presents a CFD simulation by
COMSOL multiphysics software of a metal foam heat sink
used for cooling electronic power component. The simulation is
a transient 3D of air laminar flow through a channel equipped
with a plate-electronic component system cooled by a metal
foam heat sink. The goal is to determine the thermohydraulic
behavior of the system. The foam heat sink is considered as a
porous medium, the Darcy-Forchheimer-Brinkman model is
used. We discussed the effects of air velocity, heat flux
dissipated by the electronic device and the type of metal foam
on the system phenomenology.
