The heat transmission performance of \mathrm{Al}_{2} \mathrm{O}_{3} / \mathrm{H}_{2} \mathrm{O} nanofluid in natural convective inside an enclosure with an active thermal source placed in the bottom wall is examined numerically by employing lattice Boltzmann method (LBM). The statistics focused specially on the influences of different key factors, the concentration of nanoparticles \varphi fro...Show More
In this paper, single relaxation time (SRT) and multi-relaxation time (MRT) lattice Boltzmann method are used to simulate gas flow in a lid-driven micro-cavity. Simulation of such microflow requires suitable boundary conditions. In this work, a diffuse scattering boundary condition and a combination of bounce-back and specular boundary conditions are employed to obtain the slip velocity at the wal...Show More
The buoyancy-driven gas flow (air) confined within an enclosed square-section cavity with isothermal walls is investigated numerically using the lattice Boltzmann method (LBM). The right side of the enclosure is partially heated by a hot chip, while, the left one is completely kept at cold temperature. However, the horizontal walls and apart from the chip are kept adiabatic. The buoyancy effect in...Show More
