CFD Simulation of Air Flow through a Copper Foams Fin Heat Sink under Forced Convection

  • Ban Hamed Abdullah, Abbas J. Jubear


Open-pore metallic foams have been used in a variety of applications in recent years due to essential characteristics such as low weight compared to size, high permeability, and efficient thermal performance. The thermal performance of an open-celled copper finned heat sink was examined numerically under forced convection in this study. The copper foam used in the numerical analysis is open-celled, with 90 percent porosity and 15 pores per inch (PPI) . The heat sink fins are mounted on a (100 * 100 * 3) mm3 solid copper plate. The heat input range was (5, 10, 15, 20, 25, and 30) Watts. The flow is incompressible  and turbulent in all cases of analysis.

The thermal behaviour of the foam heat sink was simulated using ANSYS Fluent R19.0 software. The air velocity values evaluated in this analysis were (1, 2, 3, 4, and 5) m/s. In addition, the fin thickness was varied to (10, 20, 30, and 40) mm. The numerical investigation also included five additional heat sink configurations. These variants were made by varying the height and arrangement of the fins while keeping the total volume constant.

The simulation study results include the difference between the base and ambient temperatures, the temperature distribution of the heat sink, and the Nusselt and Reynold numbers. The ideal air flow velocity is discovered to be 3 m/s. In terms of the influence of a single fin thickness, a fin thickness of 40 mm produces an 8.8 percent improvement over a thickness of 10 mm. Among the five heat sink designs, the model with six fins and a height of 66.67 mm outperforms the others by 10.8 percent.
