Abstract-This paper examines the natural convection in a square enclosure filled with a water-Al 2 O 3 nanofluid and is subjected to a magnetic field. The side walls of the cavity have spatially varying sinusoidal temperature distributions. The horizontal walls are adiabatic. Lattice Boltzmann method (LBM) is applied to solve the coupled equations of flow and temperature fields. This study has been carried out for the pertinent parameters in the following ranges: Rayleigh number of the base fluid, Ra=10 3 to 10 6 , Hartmann number varied from Ha=0 to 90, phase deviation (γ=0, π/4, π/2, 3π/4 and π) and the solid volume fraction of the nanoparticles between Ø = 0 and 6%. The results show that the heat transfer rate increases with an increase of the Rayleigh number but it decreases with an increase of the Hartmann number. For γ=π/2 and Ra=10 5 the magnetic field augments the effect of nanoparticles. At Ha=0, the greatest effects of nanoparticles are obtained at γ = 0 and π/4 for Ra=10 4 and 10 5 respectively.

This research is to examine the laminar, incompressible free convective Navier slip flow between vertical plates with cross diffusion effects. This investigation includes the first order chemical reaction also. The resulting equations with boundary conditions are reduced into dimensionless form using suitable transformations. Homotopy analysis method has been applied to solve the system. The influence of emerging parameters on fluid flow quantities have been presented graphically. In addition, the nature of physical quantities are shown in tabular form.

“…In their study, the analytical expressions for velocity, temperature, and mass fraction profiles are obtained and the conditions of flow reversal are analyzed for both the cases UHF and UHT. Fattahi et al (2012) applied the lattice boltzmann technique to study the nature of free convection flow of nano fluids in a square cavity. Huelsz and Rechtman (2013) also applied the lattice boltzmann technique for Heat transfer in an inclined square cavity due to natural convection of air in the laminar regime as both the Rayleigh number and the inclination angle of the cavity change, in which the range of the inclination angle covers a whole revolution.…”

This present investigation carried out the effects of Hall current, Joule heating and the thermal diffusion on mixed convection flow of electrically conducting couple stress fluid in a vertical channel saturated with porous medium. The final system of ordinary differential equations are obtained from the governing non-linear partial differential equations by using the similarity transformations. Homotopy Analysis Method has been used to solve the non-linear system. The average residue errors of the HAM solutions are presented through graphs. The influence of the emerging parameters (Hall, Soret, magnetic and the couple stress parameters) on velocity, temperature and concentration profiles are presented through plots. Finally heat and mass transfer rates at both the plates are presented in tabular form.
