Abstract
The water permeability, form drag coefficient and heat transfer coefficient of porous copper samples manufactured by the Lost Carbonate Sintering process were measured and analyzed. The permeability increased and the form drag coefficient decreased with increasing porosity and decreasing pore size. There existed an empirical relationship between the form drag coefficient and the permeability. The highest heat transfer coefficient was observed at an optimum porosity of 60%, where heat removal by conduction and convection was balanced. Larger pore sizes led to higher heat transfer coefficients due to increased tortuosity and enhanced heat transfer by convection. The best overall heat transfer performance with a combination of high Nusselt number and low friction factor was achieved at the porosity of 65%.
