ANALYSIS OF HYDROTHERMAL AND SECOND LAW OF THERMODYNAMICS FOR H2O-Cu NANOFLUID FLOW IN A CHAMBER WITH DIAGONAL WALLS IN THE PRESENCE OF AN ORIENTED MAGNETIC FIELD

In this research, the hydrothermal and irreversibility behaviors of forced convection flow of water-copper (H₂O-Cu) nanofluid under the influence of an oriented magnetic field in a chamber with diagonal walls are investigated. To reach this aim, the streamlines and temperature contours and also distributions of friction coefficient, Nusslet number, and entropy production number (Ns) are assessed against the different magnitudes of Cu nanoparticle concentrations and the intensity and orientation angle of the magnetic field. It should be noted that the magnitudes of NS are computed according to the second law of thermodynamics. It could be found that the Hartmann number and orientation angle of the magnetic field change both the trend and the values of the hydrodynamic, thermal, and irreversibility attributes, while the concentration of Cu nanoparticles only affects the magnitudes of those. However, the results of this paper may be beneficial in the design of many engineering and thermal equipment.
