Heat Transfer Enhancement with Elliptical Tube Under Turbulent Flow Tio2-Water Nanofluid

Heat transfer and friction characteristics were numerically investigated, employing elliptical tube to increase the heat transfer rate with a minimum increase of pressure drop. The flow rate of the tube was in a range of Reynolds number between 10000 and 100000. FLUENT software is used to solve the...
