Thermal Conductivities

In this study, a series of sintered nickel-copper wicks with different ratios of copper powders in the mixture of wicks were fabricated, with the effective thermal conductivities (ETC) experimentally investigated by using the steady-state method. The ETC of wick with composition of 60% nickel and 40% copper presents the lowest value among the tested range. Comparisons of some existing models for predication of porous effective thermal conductivity to experiment results were performed, but no reasonable accurate predictions were found for the tested Ni-Cu wicks.
