Abstract Traditional methods of enhancing the thermal efficiency of heating furnaces in continuously producing oilfields, such as replacing existing units with
more efficient units or renovating old furnaces, are highly inconvenient. This paper studied on the characteristics of nanofluids, a novel heat transfer
medium with excellent heat transfer characteristics to enhance the thermal efficiency of heating furnaces. The stable nanofluids (Al2O3-H2O, SiO2-
H2O, and TiO2-H2O) were prepared by a two-step method and various chemical and physical treatments were carried out. Thermal conductivities of
the nanofluids were measured using the transient hot-wire method. Based on the analysis, the most appropriate nanofluid (TiO2-H2O)… More >
