The Use of Lattice Boltzmann Numerical Method for Prediction of Nanofluid Flow in a Square Enclosure

Abstract:

In this paper, we contribute to another record of computational results by lattice Boltzmann on the flow behavior of nanofluid in a differentially heated enclosure. In the present study, numerical prediction of CuO and Al₂O₃ nanofluid, Rayleigh number ranges 10³ - 10⁵, aspect ratios of 0.5, 1.0 and 2.0 and nanoparticle volume fractions of 1, 3, 5 and 10% were performed. The results show that, for both nanofluids, increases the volume fraction lead to increase of the average Nusselt number for the whole range of aspect ratios and Rayleigh numbers.
