RT Journal Article ID 3d4a6e366e382215 A1 Hooman, Kamel T1 An Exact Solution for Fully Developed Temperature Distribution in Laminar Steady Forced Convection Inside Circular Tubes with Uniform Wall Temperature JF Heat Transfer Research JO HTR YR 2003 FD 2003-09-01 VO 34 IS 3&4 OP 11 AB In this paper the fully developed temperature distribution in laminar steady forced convection inside circular tubes with uniform wall temperature has been obtained using an exact analytical procedure. Up to now, the procedure for obtaining the temperature profile was a trial and error method. Kakac, Shah, and Aung [1], have reported an unpublished paper that proposed the solution in the form of a power series (cited in [1]). Any of the above processes seems quite sufficient to find the Nusselt number. However, a strictly exact analytical procedure does not exist. The aim of the present paper is to fill this gap in the literature. A numerical solution is also reported here. To achieve this goal a finite difference backward scheme with the truncation error of O(0.001) is utilized. It is observed that the results agree perfectly with those found by analytical solution. The agreement between the results of these two methods — numerical and analytical — left no suspicion that our analytical solution is the correct answer of the problem published for the first time.
