Abstract

This paper describes an experimental study on convective heat transfer and flow behaviour of SiO2/water nanofluids at different concentrations (5, 16 and 34 % in weight) inside a 1.3mm diameter tube heated at constant heat flux. The experimental test bench allowing us to measure local wall temperatures as well as fluid inlet/outlet temperatures is described. The flow regimes range from laminar to turbulent in the heated tube.
