Abstract
This research work attempted to analyze the impact of a magnetic field having various inclination angles on the hydrothermal convective flow and heat transport phenomena in an inverted T-shaped porous enclosure saturated with water-based hybrid nanofluid. Firstly, a comparative study for accessing the significance and applicability of the hybrid nanofluid over simple fluid (water) is accomplished at various Rayleigh numbers. Furthermore, the generalized Darcy-Forchheimer-Brinkmann model having magnetic forces is numerically simulated through the penalty finite element approach. The complete study covers the parametric studies in the presence and absence of magnetic field for parameters, including the broad-ranging values of Hartmann number (Ha), inclination angles of magnetic field (ζ), Rayleigh number (Ra), porosity (∈), and Darcy number (Da). Moreover, results obtained from the parametric studies are graphically demonstrated through the isotherms, streamlines, and the variation of mean Nusselt number plots (Nu<sub>m</sub>). The results variation suggests that the heat transfer rate is getting more robust with Da, Ra, and ∈, though the appearance of the magnetic field restricts the fluid flows and heat transport. Additionally, the increasing angle supports the heat transfer process till ζ = 30 up to some extent, and further, it deteriorates till ζ = 90. Thus, a proper inclination and the magnitude of the magnetic field may be a better choice to control the flow regime and the thermal transport phenomena inside the porous domain.
