Convection Inside Nanofluid Cavity with Mixed Partially Boundary Conditions

In recent decades, research utilizing numerical schemes dealing with fluid and nanoparticle interaction has been relatively intensive. It is known that CuO nanofluid a volume fraction of 0.1 special thermal boundary condition heat supplied to part the wall increases average Nusselt number for different aspect ratios ranges high Rayleigh numbers. Due its simplicity, stability, accuracy, efficiency, ease parallelization, we use single relaxation time Bhatnagar-Gross-Krook (SRT BGK) mesoscopic approach D2Q9 scheme lattice Boltzmann method in order solve coupled Navier–Stokes equations. Convection square enclosure moderate 105 new conditions highlighted. After successful validation simple partial Dirichlet condition, this paper extends study deal linear sinusoidal applied wall.
