Steady laminar heat transfer in a circular tube with prescribed wall heat flux

An analysis is performed to determine the heat transfer characteristics for a laminar forced convection flow in a circular tube with prescribed wall heat flux. Results are first obtained for the case of uniform heat flux, and these are then generalized to apply to the situation of arbitrary longitudinal variation of wall heat flux. The solution contains a series expansion whose form is similar to that obtained by Graetz for the uniform wall temperature problem.
