The Effect of Axial Heat Conduction on the Thermal Development of a Heat-Generating Fluid

An analysis is made to determine the heat transfer characteristics for steady, fully developed flow of a heat-generating fluid between isothermal parallel plates. Axial conduction is not neglected and the velocity profile is assumed to be nonuniform in the transverse direction. The results indicate that axial conduction is a low Peclet-number thermal-entrance region effect and increases or decreases Nusselt numbers depending on the heat-source strength and the boundary conditions.
