Thermal influence of heated fin on MHD natural convection flow of nanofluids inside a wavy square cavity
MHD free convective thermal transport and fluid flow in a square cavity with the top wavy wall and a heated single fin that is attached vertically at the middle of the bottom wall filled with Al2O3-H2O nanofluid is studied numerically. The top wavy wall is heated at a low heat T = Tc while the left,...

| description | MHD free convective thermal transport and fluid flow in a square cavity with the top wavy wall and a heated single fin that is attached vertically at the middle of the bottom wall filled with Al2O3-H2O nanofluid is studied numerically. The top wavy wall is heated at a low heat T = Tc while the left, right, and, bottom walls are insulated. The fin is heated at a high-temperature T = Th (Th > Tc). Galerkin's weighted residual-based finite element techniques are utilized for solving the mathematical model. Compared with the published work, the results are validated excellently. Streamlines and isothermal contours are displayed here for different pertinent parameters like Rayleigh number, nanoparticles volume, and Hartmann number. The outcome depicts that for the increasing value of all these parameters, the temperature flow changes significantly. The average Nusselt number also changes significant with the nanoparticles volume, Rayleigh number, and Hartmann number. With the changes of fin length, the changes in streamlines and isotherms are also observed. Additionally, to investigate the best heat transfer performance, various form of nano-sized particles is also investigated. The nanoparticle shape factor has a great influence in temperature transportation. Moreover, the temperature transport rate increases by 7.65% for the blade-shaped nanoparticles, whereas it increases by 2.86% for spherical-shaped nanoparticles. |
