In this study, heat transfer characteristics in the presence of a conducting body placed in an enclosure are 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 different thermal conductivity ratios, sizes, shapes, locations, and numbers of the solid bodies and of the Rayleigh number on heat transfer is observed by isotherms and average Nusselt number. A way to determine the stream function boundary condition around solid body is also proposed.
