Large eddy simulation of turbulent natural convection of nanofluids in a T-shaped channel

In the present work, turbulent natural convection in a T-shaped enclosure that filled Cu/water as nanofluid is analyzed. Large eddy simulation (LES) is used as turbulent model and in order to numerical simulation; lattice Boltzmann method (LBM) has been handled. The effect of some important parameters in nanofluid and natural convection like solid volume fraction on the temperate distribution in the domain is studied. The validation of the present code is done with the other published results, and there is a good agreement between them. The obtained results show that using nanofluid, due to the high conductivity copper particles, can enhances the heat transfer rate and also causes average Nusselt number increased too.
