Investigation of the effect of the internal heating system position on heat transfer rate utilizing Cu/water nanofluid

The present study has been examined the effect of the heating system position in a cubic cavity on the heat transfer rate. Also, the effects of adding the nanoparticles to the based fluid for the various heating system positions have been considered. Double multi-relaxation time lattice Boltzmann method has been used in this study as the numerical method. The position of the heating system has been varied from the bottom to the top of the room with H /4 interval ( z HW = 0 , H 4 , H 2 , H ). Cu/water nanofluid has been used to consider the effects of nanoparticle. Results have been presented for the various parameters such as Rayleigh number (10 3
