Abstract:Nanofluids refer to new kinds of engineering materials which are prepared by dispersing fine nanometer sized particles (smaller than 100 nm) in a base fluid. It has been recognized in the past decade that nanofluids have higher thermal properties compared with the base fluids. In this work nanofluids were prepared by dispersing γ-Al2O3 and CuO nanoparticles in engine oil, in different concentrations up to two volume percent. The thermal conductivity and the heat capacity were measured at different temperatures. Experiments revealed the enhancement of the thermal conductivity and the decrease of the heat capacity.
