Description
Summary:In this work, heat transfer enhancement of different nanofluids laminar flow in pipe is numerically studied. The flow of turbine oil as base fluid with Al2O3 nanoparticle for the heat transfer enhancement is examined with different volume fractions (0-4 %). The nanofluids are modeled with constant thermophysical parameters. The heat transfer results are provided using single-phase method, Newtonian behavior at Reynolds number Re=915. The result reports the impact of the volume fraction on the thermal boundary layer and heat transfer. For constant Reynolds number the velocity increase as the volume fraction increase. However, the temperature decreases as the volume fraction increases meaning better heat transfer occurred. The highest transfer was obtained for turbine oil–Al2O3 with volume fraction 4%.
