Abstract
This research paper performs a numerical investigation on Nano-fluid's laminar flow and the effect of their thermo-physical characteristics on convective heat transfer. Thus, Ag-Al2O3/H2O hybrid Nano-fluid was chosen based on its excellent properties and a magneto-hydrodynamic flow analysis inside of a modified trapezoidal porous enclosure has been conducted. Using the Darcy-Forchheimer-Brinkmann model and the finite element method to resolve the non-dimension equations, the exploitation was carried out by altering Rayleigh, Darcy, Hartmann, and the volume fraction of the hybrid Nano-fluid. The outcomes revealed intriguing results, supporting the augmentation of Ra, Da, and phi to improve the average Nusselt and boost thermal transfer, and recommending that Ha should be decremented. Furthermore, the findings of this study evaluated the geometrical features of the trapezoid and indicated that decreasing the aspect ratio of the enclosure, the undulation number of the wall, and raising the inclination angle of the side walls are critical for prolonged thermal efficiency and heat transmission.
