摘要: Abstract In this study the lattice Boltzmann method is applied to investigate effect of magnetic field on natural convection heat transfer Al 2 O 3 –water nanofluid in a two-dimensional horizontal annulus. model, Brownian motion effective thermal conductivity also considered. The and viscosity are calculated by KKL (Koo–Kleinstreuer–Li) correlation. nanoparticle volume fraction for enhancement was examined several sets values Rayleigh Hartmann numbers. Also, correlation Nusselt number with physical parameters presented. obtained results indicate that value maximum stream function decreases increasing number. Furthermore, we notice has direct relationship number; but quite opposite true Lattice double-population powerful approach simulation nanofluids regions curved boundaries.
