Experiments are performed by measuring a developing thermal plume in an enclosure, that is generated by a constant heat flux annular cylinder heater, with six T-type thermocouples. An empirical correlation obtained among local Nusselt number, Fourier number, and modified Rayleigh number is Nux /Rax *1/4 = 0.00422FoL −0.893 .
