Abstract: The innovation of this paper is fins shape and arrangement effects on entropy generation and hybrid fluid-solid-fluid heat transfer in 3D multi-floors enclosure with heat flux boundary condition by lattice Boltzmann method (LBM). The results signified that maximum and minimum of mean non-dimensional temperature on the wall (z = 0) were in enclosure with 22 rectangular fins in hot and cold zones that was equal to 0.503 (15.1%) and five horizontal ellipse fins in hot zone that was equal to 0.445 (1.8%), respectively.

Keywords: different fins arrangement; entropy generation; fluid-solid-fluid interface; heat flux; hybrid thermal field; lattice Boltzmann model.
