A honeycomb-structured ceramic porous plate (HPP) is used
for the CHF enhancement in a saturated pool boiling. HPP is
commercially available as a filter for purifying exhaust gases
from combustion engines. This honeycomb porous plate has
considerably smaller micro-pores on the order of 0.1 m, as
compared with those for sintered metal powders, and is simply
attached to the test surface without any treatment, such as
spraying or sintering. Moreover, the CHF has been enhanced
experimentally up to approximately three times that of a plain
surface (approximately 320 W/cm2) with a heated surface of 30
mm in diameter. In this paper, we will show the CHF
enhancement mechanism using HPP as well as further CHF
enhancement techniques by combination of HPP and nanofluid.
