ABSTRAKT

In this study, laminar mixed convection of alumina/water nanofluid flow in a horizontal grooved channel with internal heat generating solid cylinders in the presence of a magnetic field has been studied. The simulation is carried out in the ranges 50 ≤ Re ≤ 100, 0 ≤ Ha ≤ 100, 5000 ≤ Gr ≤ 10,000, and 0 ≤ φ ≤ 0.04. The results show that at a constant Grashof number, an increase in the Reynolds number and volume fraction of nanoparticles causes the convective heat transfer coefficient to increase. Also, at a constant Reynolds number, as the Hartmann number increases, the average Nusselt number increases. In addition, an increase in the volume fraction of nanoparticles has improved PEC at all Reynolds and Hartmann numbers. Also, at a constant volume fraction, as the Hartmann number and Reynolds number increase, the heat transfer coefficient increases. In addition, by adding nanoparticles to the base fluid, the average Nusselt number increases. When the Reynolds number is 50, the percentage increase of Nusselt number with a volume fraction of 3% relative to the base fluid is 4.97%.
