Finally, though, a rise in the size of the confined heat source enhances the rate of total thermal transport, it does not change the trend of fluid flow and local heat transfer rate. e-mail:  m.sivasubrahmanyam@gmail.com e-mail:  pkd@mech.iitkgp.ernet.in 23 04 2020 05 12...

..., and the local heat transfer rate around the outer cylinder are very sensitive to the location of the heating element. The heating element Nusselt numbers at various locations on the inner cylinder are obtained and well correlated against the Rayleigh number to the 1/3 powers. A maximum in the correlation...
