摘要

This paper investigates a steady mixed convection in a lid-driven square cavity subjected to an inclined magnetic field and heated by corner heater with an inserted square solid block. Water-Al2O3 nanofluid fills the cavity based on Buongiorno's two-phase model. A corner heater is configured in the left lower corner of the cavity by maintaining 40 of the bottom and vertical walls at constant hot temperature. The top horizontal wall is moving and maintained at a constant low temperature. The remainder walls are thermally insulated. The governing equations are solved numerically using the finite element method. The governing parameters are the nanoparticles volume fraction (0 = phi = 0.04), Reynolds number (1 = Re = 500), Richardson number (0.01 = Ri = 100), Hartmann number (0 = Ha = 50) and the size of the inner solid (0.1 = D = 0.7). The other parameters: the Prandtl number, Lewis number, Schmidt number, ratio of Brownian to thermophoretic diffusivity and the normalized temperature parameter, are fixed at Pr = 4.623, Le = 3.5 x 10(5), Sc = 3.55 x 10(4), N-BT = 1.1 and delta = 155, respectively. The inclination of the magnetic field is fixed at gamma = pi/4. Results show that at low Reynolds number, the increase in nanoparticles loading more the 2 becomes useless. It is also found that a big size of the solid block can augment heat transfer in the case of high values of both the Reynolds and Richardson numbers.
