Abstract

This study was conducted to investigate the effect of magnetic field on Hartmann numbers ranging from 50 to 200 in a parabolic solar collector with zero to 2.25 percent volume fraction of magnetic hybrid nanofluid containing three nanoparticles of iron oxide, multi-walled carbon nanotubes, and copper in the Reynolds number range of 18000 to 42000. In the numerical study, a parabolic solar collector was simulated using the finite volume method, and the thermophysical properties of the magnetic hybrid nanofluid were used as the working fluid in it. The solar collector absorber tube under study is equipped with three different geometric shapes of turbulators. A hybrid nanofluid of water/carbon nanotube multi-wall-iron oxide-copper has been considered for two-phase simulation. According to numerical results, the maximum exergy efficiency is related to the absorber tube equipped with a combination of turbulator and circular wire. Additionally, the maximum exergy efficiency is related to a Reynolds number of 18000 at a Hartmann number of 200.
