摘要：

Nanosized α-Al2O3 powder with a specific surface area (SSA) of 25 m2g-1 was used as the solid phase. Deionized water (H2O), glycerol (Gly), ethylene glycol (EG), and pump oil (PO) were used as base fluids. Nanoparticle-fluid mixture was prepared by dispersing the desired volume fraction of nanosized αAl2O3 powder into a base fluid in a mixing container. Solid particles were deagglomerated by intensive ultrasonification after mixing with the base fluid, and then the mixture was homogenized by magnetic force agitation. The thermal conductivities of the mixtures were measured by a hot-wire method.
