Mathematical simulation of forced convection in an axis-symmetric channel at local heating of the wall

This research is devoted to mathematical modeling of forced convection in a circular tube having an annular wall heating. Two heating conditions are considered, namely, a constant temperature and a constant heat flux at the heating section. The solution is obtained numerically using the finite difference method. Mathematical correlations are obtained to reflect the nature of the dependence of the average Nusselt number on the Reynolds and Prandtl numbers, which varied in the ranges 50 ≤ Re ≤ 500 and 0.7 ≤ Pr ≤ 100, respectively.
