Modelling of Convective Heat Transfer of Nanofluid in Inversed L-Shaped Cavities

Abstract

Research on nanofluids has been quite intensive in the past decade. Whilst there have been many studies analyzing the performance of nanofluids, the behavior of nanofluid confined in complicated geometry, especially those using numerical simulation, are scarce. In this study, the behaviors of nanofluid in inverse L-shaped of cavity were simulated using in-house matlab code. The cubic interpolated pseudo particle method was used to solve the governing equation of nanofluid. The results showed improvements in terms heat transfer with the presence of nanofluid and the nanoparticle volume fraction significantly increase the Nusselt number in the enclosure. Analyses on the aspect ratio, Rayleigh number, nanoparticle volume fraction and thermal conductivity of nanofluid showed their significant effect on the performance of the nanofluid confined in inverse L-shaped of cavity.
