“…Very recently, Naganthran et al (2018) studied the effect of thermal radiation on mixed convection flow over a permeable vertical shrinking flat plate. Udhayakumar et al (2016) investigated the effects of magnetohydrodynamic mixed convection over an isothermal circular cylinder in presence of an aligned magnetic field. Meanwhile, Hussain et al (2016) studied on mixed convection in a double lid-driven cavity filled with nanofluid and the cavity is imposed to entropy generation along with discrete heating.…”

Effects of magnetic field inclination on fluid flow and heat transfer in a two-dimensional square cavity are analyzed numerically. The vertical walls are well insulated, the bottom wall is maintained at a cold temperature, while the top moving lid is kept at a hot temperature. The finite volume method and SIMPLE algorithm are employed to solve the dimensionless governing equations. The results are presented by the profile of streamlines and isotherms, and the variation of Nusselt number. Mixed convection flow is retarded by the presence of the magnetic field and the average Nusselt number is an increasing function of the magnetic field angle.

“…They found that the average Nusselt number decreases with the increasing of Richardson number and Hartmann number. A finite difference scheme was developed to investigate MHD mixed convection over an isothermal circular cylinder in the presence of an aligned magnetic field [12]. They claimed that the fluid flow with large mixed convection can be better controlled with the help of external applied magnetic field.…”

In the present study, a three dimensional thermal lattice Boltzmann model was developed to investigate the flow dynamics and mixed convection heat transfer of Al2O3/water nanofluid in a cubic cavity in the presence of magnetic field. The model was first validated with previous numerical and experimental results. Satisfactory agreement was obtained. Then the effects of Rayleigh number, nanoparticle volume fraction, Hartmann number and Richardson number on nanofluid flow dynamics and heat transfer were examined. Numerical results indicate that adding nanoparticles to pure water leads to heat transfer enhancement for low Rayleigh numbers. However, this enhancement might be weakened and even reversed for high Rayleigh numbers. In addition, the results show the external applied magnetic field has an effect of suppressing the convective heat transfer in the cavity. Moreover, the results demonstrate that the Richardson number in mixed convection has significant influences on both streamlines and temperature field.

“…The Coriolis force exerts a strong influence on the hydromagnetic flow in the earth's liquid core which plays an important role in the mean geomagnetic field. Selvarasu et al [3] studied the effect of magnetic field on the steady, laminar flow of an incompressible and electrically conducting fluid with mixed convection. The flow and temperature fields for low Re was considered.…”
