Research Abstract |
With the aim of enhancing heat transfer in the SiC heat exchanger, a nano- and micro-structured surfaces made of carbon nanotubes (CNTs) by surface decomposition of SiC and bonded with a porous SiC plate were produced on SiC substrates. The effect of heat transfer enhancement by these nano- and micro-structured surfaces were examined by a convective heat transfer test using water. The nano- and micro-structured surface on the CVD-SiC with hydrophilicity was the only surface that showed any heat transfer enhancement. The surface wettability was related to heat transfer enhancement of the nano- and micro-structured surface.
