Abstract: In this research, conjugate heat transfer of incompressible laminar flow inside a two -dimensional cavity with two vertical conductive partitions have been studied numerically using lattice Boltzmann method (LBM). The enclosure has been filled by water-(Al2O3) nanofluid. The present study scrutinized the effect of aspect ratio of partitions and position of them on the top and bottom walls. The results have been validated with previous research, and the excellent agreement have been found between the results. The hydrodynamic and thermal behavior of the nanofluid in the presence of rectangular partitions have been investigated in the format of streamlines, isotherms, and average Nusselt number. The results of this simulation showed that rectangular partitions have a significant influence on the flow, temperature, and heat transfer rate. In addition, the average Nusselt number showed an increasing function by increment the Rayleigh number in the range of 103−106 and nanofluid volume fraction in the interval of 0–0.05. The investigating of different ratio of partitions, it is illustrated that by decreasing the height and thickness ratio, the heat transfer rate will be enhanced.
