Abstract

Forced convective laminar flow of different types of nanofluids such as Al₂O₃ and SiO₂, with a nanoparticle size of 30nm, and different volume fractions ranging from 0.5% to 1% using water as base fluids were investigated numerically and experimentally. This investigation covers the Reynolds number in the range of 90 to 160. The results have shown that SiO₂-water nanofluid has the highest Nusselt number, followed by Al₂O₃-water, and lastly pure water. The maximum heat transfer enhancement was about 22% when using the nanofluids and the numerical and experimental results agree well with the conventional theory.
