Abstract: | An analysis has been carried out to determine the heat transfer characteristics for fully developed turbulent flow in concentric annular ducts with constant thermal boundary conditions of second kind. The energy equation has been solved analytically by separation of variables. Results for heat transfer in the thermal entrance region, in the thermal fully developed flow and thermal entrance-length results are presented over a wide range of Reynolds number (104?Re?106) and Prandtl-number (0?Pr?100) and compared to available empirical data. |
