Effects of thermal conductivity and wettability of porous ...

The thermal resistance can be tuned by the thickness and the porosity of a sample. When the thermal conductivity is fixed, a high wettability will enhance the boiling heat transfer because of the enlarged bubble-separation frequency. 2) A sample with a small porosity could have a high thermal conductivity which is benefit for boiling heat transfer.
