Abstract
In the present research, aluminum oxide- water (Al2O3-H2O) nanofluid free convection due to magnetic forces through a permeable cubic domain with ellipse shaped obstacle has been reported. Lattice Boltzmann approach is involved to depict the impacts of magnetic, buoyancy forces and permeability on nanoparticles migration. To predict properties of Al2O3- water nanofluid, Brownian motion impact has been involved. Outcomes revels that considering higher magnetic forces results in greater conduction mechanism. Permeability can enhance the temperature gradient.
Highlights
By suggesting nanoparticles from nanoscience as useful working fluid, thermal performance enhances
Numerical outputs are depicted the variations of magnetic force (Ha = 0 to 60), buoyancy term (Ra = 103, 104 and 105) and Darcy number (Da = 0.001 to 100)
Uniform magnetic force impacts on momentum equations were considered in a 3D porous enclosure
Summary
Adiabatic and hot surfaces are depicted in this graph. One direction magnetic force has been involved. To find the temperature and velocity, distribution functions were used namely (g and f)
