【 摘 要 】

An experimental study on forced convective heat transfer and flow thermophysical properties of a nanofluid consisting of three various concentrations of Al2O3 nanofluids (0.13, 0.25 and 0.64%) vol.% and deionized water which flows in a cooling coil made of copper pipe (heat exchanger) under laminar flow conditions are investigated. The Al2O3 nanoparticles of 90 nm diameter are used in this study. Working fluid flow rate of 0.5 L/min to have the fully laminar regime (1320.42O3/deionized water nanofluid when concentration 0.64 vol.% is slightly higher than that of the deionized water alone at same conditions (inlet temperature and mass flow).
