摘要：

We present data for the thermal conductivity of nanofluids consisting of two sizes of ceria nanoparticles dispersed in water at 298 K. We also demonstrate that the effective thermal conductivity of these heterogeneous nanofluids can be described by a simple "mixing" rule that incorporates the size dependence of the thermal conductivity of the nanoparticles themselves. Our data follow the same trends with particle size as shown for alumina nanofluids in our previous work, and provide additional validation for that data.
