The H2 forced convection in a rectangular duct of large aspect ratio is studied. It is found that the short ends have non-negligible effects on the Nusselt number and the temperature distribution. The Nusselt number at large aspect ratios depends on the net heat addition from the ends, but not how they are distributed.
