Özet

In this study, heat transfer characteristics in presence of a conducting body placed in the center of a unit square cavity is investigated by using the dual reciprocity boundary element method (DRBEM). The governing dimensionless equations in terms of stream function, temperature and vorticity are solved numerically, and the effect of the different thermal conductivities and sizes of the solid body on heat transfer is observed by isotherms and average Nusselt number. Thermal conductivity loses its effect on heat transfer in large Ra numbers, and the increase in the size of the body with a small conductivity and large Ra enhances heat transfer.
