This paper presents numerical and CFD simulation of an Al 2 O 3 -water nanofluid turbulent flow in a circular pipe which has a 36 mm diameter with a constant heat flux at the pipe wall using ANSYS FLUENT 2020 R2. The turbulent flow under different Reynolds numbers, from Re = 10000 to 50000 was used to process the numerical experiments. Different concentrations of nanoparticles, ranging from 1% to 4%, were used. The results were computed utilizing the single-phase approach. The coefficient of transfer of heat of nanofluids is found to be greater than that of base liquid. Enhancement in transfer of heat is also observed with rising in volume concentration of particles.
