Description: A numerical model for heat transfer in laminar duct flows has been developed using the finite difference method      to explore the significance and extent of "back-conduction" at low Peclet numbers. The calculations have been      carried out for flows between parallel plates and in circular tubes by using different Peclet numbers in the range      of 0.05 to 100. For both situations constant heat flux and constant wall temperature boundary conditions were      used. The validity of the results has been checked by comparison with some existing results in the literature, and      extended to a wider range of parameters including conjugate wall conduction effects. The results are presented      for bulk mean temperature variation, Nusselt number behavior, and energy absorbed before the heated section,      for cases with and without wall conduction. Such axial conduction effects may be an important feature in the      thermal characterization of microtubes, which are to be used in microheat exchangers.
