Abstract text:
The heat transfer of nanofluids in a coaxial heat exchanger is studied numerically using a Computational Fluid Dynamics (CFD) approach. The present study indicates an increase of the thermal performances with 50% of nanofluids compared to water. The nanofluid is composed of aluminum oxide (Al2O3) particles dispersed in water for various concentrations ranging (1, 3 and 5%).
Key Words:
nanofluid; Nusselt number; Reynold’s number; heat transfer.
