Pool boiling CHF enhancement using a honeycomb porous plate and nanofluid

A honeycomb-structured ceramic porous plate (HPP) was used to increase the critical heat flux (CHF) in a saturated pool boiling. Combining the HPP with a nanofluid significantly improved the CHF compared to that obtained from a plain surface in pure water, to a maximum of approximately 3.2 MW/m2. In...
