Use of Hybrid Nanofluid to Increase Heat Transfer Performance of Double Pipe Heat Exchanger using CFD

In present work, forced convection of a turbulent flow of, Al2O3 water nanofluid and Al Al2O3 water hybrid nanofluid a new advanced nanofluid composited of Al and Al2O3 nanoparticles through a double pipe heat exchanger is numerically analyzed. The solid model of the double pipe heat exchanger is created in design modular and analyzed by the computational software ANSYS 16.0.This work examines the effects of these two fluids as the working fluids, a wide range of Reynolds number 20000 = Re = 60000 and also the volume concentration 0.25 , and 0.5 on heat transfer and hydrodynamic performance. The finite volume discretization method is employed to solve the set of the governing equations. The results indicate that employing hybrid nanofluid improves the heat transfer rate with respect to nanofluid. However, the average increase of the average Nusselt number when compared to nanofluid in Al Al2O3 water hybrid nanofluid is 14 and the amount for the average increase of heat transfer coefficient would be 27.5 .
