Potential Applications

Carbon foams have potential applications in thermal management of electronics and aerospace industries due to their low density and high thermal conductivity. These foams have open or closed pores that are approximately spherical. This paper presents a finite element analysis of the thermomechanical properties of carbon foams with randomly distributed spherical pores. The results are presented in nondimensional form and compared with theoretical and finite element analysis values obtained for cellular foams. The effect of pore distribution on the effective thermal conductivity of foams is also presented.

Result Show

The effect of diamond shape on the thermal conductivity of diamond/Cu composites was studied by combine finite element method with the tests. The finite element result show that the thermal conductivity of the hexoctahedron diamond/Cu composites and the square diamond/Cu composites is 819 W/m·K and 1013 W/m·K respectively. And the testing results indicate that the thermal conductivity of the single hexoctahedron diamond/Cu composites and the hexoctahedron mixed with the square diamond/Cu composites is 659W/m·K and 720 W/m·K respectively. The testing results consist with the finite element calculation. Under the same circumstances, more {100} faces can bring in less overall thermal resistance in the composites thus improve the thermal conductivity of the composites. The results show that using square diamond particles helps to improve the thermal conductivity of diamond/Cu composites.
