**Abstract:**

^{2}to 2426 W/m

^{2}and the Rayleigh number ranges from 1×10

^{4}to 4.35×10

^{4}. For natural air flow and constant heat flux condition, the effects of heat transfer around the cylinder under steady-state condition are investigated. The steady-state results compare favorably with that of the available data. The effects of transient heat transfer data on different angular position of the thermocouple (0

^{o}, 90

^{o}, 180

^{o}) are also reported. It is observed that the transient heat transfer around the cylinder is strongly affected by the position of thermocouples. In the transient region, the rate of heat transfer obtained at 90

^{o}and 180

^{o}are higher than that of stagnation point (0

^{o}). Finally, the dependence of the average Nusselt number on Rayleigh number for steady and transient natural convection heat transfer are analyzed, and a correlation equation is presented.
