Description

The present problem simulates the fluid flow inside a porous medium for heat sink cooling using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

Studying fluid flow in porous media is one of science's most widely used fields. A porous medium comprises mostly perforated materials and contains pores and void spaces within itself.

The present model is designed in three dimensions using Design Modeler software. The modeled geometry for this simulation consists of a hollow section acting as an inlet, followed by a porous aluminum foam, which is in contact with a heat source.

The meshing of this present model has been generated by Ansys Meshing software. The meshes used for this geometry are structured, and the total number of mesh cells is 7680.

Heat Sink Cooling Methodology

In this project, the fluid flow and heat transfer inside a porous medium is simulated by ANSYS Fluent software. This porous medium is in contact with a heat source, and the whole setup acts as a heat sink.

The flow enters through the inlet boundary with a velocity o 1.99 m/s and a temperature of 300K. It flows inside the porous medium to receive heat from it.

Moreover, the energy model is activated, and the RNG  k-epsilon model with standard wall function is exploited for fluid flow analysis.

Heat Sink Cooling Conclusion

At the end of the solution process, we obtain the temperature, velocity, pressure, streamlines, and velocity vectors.

As seen in the pressure contour, the flow pressure behind the porous medium significantly differs from that of the outlet boundary due to the resistance that the porous medium imposes on the system.
