ENHANCEMENT OF THERMAL AND ENTROPY PERFORMANCE OF CPU HEATSINK USING HYBRID NANOFLUID UNDER NATURAL MAGNETOHYDRODYNAMIC CONVECTION
The need for effective CPU cooling has become increasingly important with the growing demand for computing performance. In this paper, we numerically investigate the problem of active CPU cooling using hybrid nanofluids. The studied heatsink consists of a parallelepiped-shaped block filled with a hybrid nanofluid, crossed by four tubes through whic...

UNSTEADY NUMERICAL INVESTIGATION OF FERROFLUID FORCED CONVECTION OVER A DOWNWARD STEP CONTAINING A ROTATING FINNED CYLINDER
The unsteady investigation of ferrofluid flow forced convection over a downward step containing a rotating finned cylinder is conducted numerically. The dimensionless partial differential equations of conservation equations for mass, momentum and energy and the boundary conditions associated with them are solved by using the finite element method. ...

NUMERICAL INVESTIGATION OF THE NANOFLUID NATURAL CONVECTION FLOW IN A CPU HEAT SINK USING BUONGIORNO TOW-PHASE MODEL
In this paper, a numerical investigation using the finite element method on the cooling capacity of an electronic heat sink has been presented. This heat sink is intended for cooling applications of micro-computer CPUs. It deals with a parallelepipedal block with rectangular fins, filled with a nanofluid and crossed by four cylindrical pipes in whi...

EFFECT OF VERTICAL POSITION OF HEATED SQUARE OBSTACLE ON NATURAL CONVECTION IN POROUS CAVITIES SATURATED BY A NANOFLUID USING BUONGIORNO'S TWO PHASE MODEL
Laminar flow, heat transfer and mass transfer of nanofluid in a porous medium have been studied using Buongiorno’s two phase model. The porous medium in place is a non-uniform octagonal shape. In order to increase the rate of heat transfer within the porous cavity, it has been equipped with a heated square at different vertical p...
