Experimental investigation of forced convection of water-Al2O3 nanofluids inside horizontal tubes,

Abstract

In this paper, forced convection of water–Al2O3 nanofluids inside horizontal copper tube is studied experimentally. Experiments were conducted for three, i.e. 0.1%, 1% and 5% nanoparticle mass concentrations under transition and turbulent flow regimes. Average heat transfer coefficients and pressure drop values were determined and compared to distilled water. Enhancement of heat transfer for lower nanoparticle concentration and deterioration of heat transfer for higher nanoparticle concentration has been recorded. Substantial increase of pressure drop for nanofluids compared to distilled water has been observed.
