Abstract
A nanofluid saturated porous medium is used for cooling purposes of a plane electronic device contained in the base of a hemispherical cavity. According to the intended application in embarked electronics, the base could be tilted with respect to the horizontal plane by an angle ranging from 0[Formula: see text] to 180[Formula: see text] (horizontal disc with cupola facing upwards and downwards, respectively). The volume fraction of the considered monophasic water-based ZnO nanofluid varies between 0% (pure water) and 10%, while the Rayleigh number based on the radius of the cavity ranges from [Formula: see text] to [Formula: see text]. The ratio between the thermal conductivity of the porous medium solid matrix and that of the base fluid varies between 0 and 70. Influence of these four parameters on the average temperature of the active electronic device is presented and commented. The work shows that the saturated porous medium has a significant effect on the thermal state of the electronic device. A correlation is proposed to easily calculate this temperature for any combination of these parameters, which allows thermal sizing for optimal cooling of this assembly used in electronics engineering.
