Fig. 3 shows schematic of a rotary kiln and the symbol used for the modelling of heat transfer. It can reduces to two dimensional problems (ϕ, r) by neglecting axial thermal conduction along the kiln, as length of the rotary kiln is long enough in comparison with the diameter. This equation gives temperature distribution across the rotary kilns.
