An analysis has been made of the temperature distribution and heat transfer in a generalized, symmetrical annular space including the effects of axial diffusion of heat in the fluid with the assumption of slug flow and with arbitrary heat-flux distributions at the walls of a section between two infinitely long adiabatic inlet and outlet sections. An examination has been made of the effects produced by including axial diffusion and varying the Peclet number, the length of heated section, and the heat-flux distributions. The results may be applied to estimate the extent of the influence of axial diffusion and to correct predictions which have neglected it.
