This paper reviews the research progress of nano materials in engineering fluids. The following contents are introduced： the dispersion stability mechanism of nano engineering fluids, selection of dis- persing agent and the influencing factors ; the heat and mass transfer properties of nano engineering fluids including the coefficient of thermal conductivity, convective heat transfer, boiling heat transfer and gas- liquid mass transfer; and the experimental and theoretical research on tribological properties and anti- wear and extreme pressure performance of nanometer lubrication, in hope of providing guidance for the development of nano engineering fluids in the fields of refrigeration, heat conduction, lubrication and absorption. The problems in the development of nano engineering fluids and the developing direction are also put forward.
