Abstract
Owing to their outstanding characteristics, carbon based nanofluids (CbNFs) have been applied to various advanced heat transfer and cooling technologies. It was claimed that these CbNFs can considerably improve the properties of the base working fluids. Among all the thermal characteristics, the thermal conductivity (lambda) is regarded as the primary parameter to be considered for the application of nanofluids (NFs). In the present research study we measured for the first time both lambda and thermal diffusivity (a(T)) of very stable fullerene (C-60)-based NFs in liquid phase (1,2,3,4-tetrahydronaphthalene and 1,2-dicholorobenzene) by the transient multi-current hot wire technique at atmospheric pressure in a wide range of temperature (254-323 K). Similar to the base liquids (BLs), we observed a slight decrease in lambda with an increase in temperature. Additionally, compared to the BLs lambda was reduced upon the addition of C-60. The results were compared with the predicted ones using different theoretical models. Not much variation in a(T) was observed between the C-60 NFs and the corresponding BLs due partly to the small variation of lambda with the addition of C-60.
