摘要: Purpose – Magneto hydrodynamic (MHD) flows in fluids is known to have an important effect on heat transfer and fluid flow various substances while the quality of considered shapes can influence amount changes. Thus, MHD a different form widespread alterations kind material power were carried out by lattice Boltzmann method (LBM) this investigation. The aim paper identify ability LBM for solving as presence magnetic field changes.Design/methodology/approach This was utilized natural convection open cavity Hartmann number varies from 0 150 Rayleigh at values Ra=103, 104 105, with Prandtl altering wide range Pr=0.025, 0.71 6.2. An appropriate validation previous numerical investigations demonstrated that attitude suitable pro...
