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

In the present work, turbulent natural convection in a Tshapedenclosure that filled Cu/water as nanofluid isanalyzed. Large eddy simulation (LES) is used as turbulentmodel and in order to numerical simulation; latticeBoltzmann method (LBM) has been handled. The effect ofsome important parameters in nanofluid and naturalconvection like solid volume fraction on the temperatedistribution in the domain is studied. The validation of thepresent code is done with the other published results, andthere is a good agreement between them. The obtainedresults show that using nanofluid, due to the highconductivity copper particles, can enhances the heat transferrate and also causes average Nusselt number increased too.
