| Abstract: | The transient hot wire method is used to measure the thermal conductivities of CuO nanofluids at the different ovlume fraction and temperature.The experimental results show that nanofluids have remarkably higher thermal conductivities than those of conventional pure fluids,the thermal conductivities of nanofluids are influenced by the volume fraction of nanoparticles and temperature and the effect degree of temperature on the thermal conductivities of nanofluids is associated with the volume fraction of nanoparticles. |

| Keywords: | nanofluids temperature volume fraction thermal conductivities |
