摘要：

This paper investigates critical heat flux (CHF) in saturated pool boiling for water and TiO2 nanofluid on a 7-mm-diameter vertical copper surface at pressures of 0.1-0.8 MPa. The nanofluid was prepared by dispersing 0.002 wt% TiO2 nanoparticles in deionized water. The CHF of the nanofluid was enhanced about two times over that of water boiling at atmospheric pressure. With the increasing pressure, however, the CHF enhancement with the nanofluid decreases, and almost disappears at 0.8 MPa.
