摘要：

Surface with TiO2 nanotube arrays (TNTAs) is superhydrophilic and of great specific area. This paper investigates the pool boiling characteristics at the thermal interface with TNTAs. The results show that the TNTAs interface can enhance the pool boiling heat transfer compared to the pure Ti metal plate. The bubbles formed at the initial nucleation state are very small and released in higher frequency. The pool boiling heat transfer enhancement at the TNTAs interface may be attributed to the high density of nucleate site, high intrinsic heating area of nanotubes layer, superhydrophilicity and the vertically oriented nanotube structure.
