As duct configurations of interest in heat exchanger designs and other components in propulsion systems, a corrugated duct and a parallel plate duct with repeated rib roughness were selected for numerical modeling. For the rough duct, the flow field and the temperature distribution in both the fluid and in the solid plate were obtained. Results for the corrugated duct reveal the presence of large recirculating zones at Reynolds numbers greater than about 50. The friction factor passes through a minimum as the Reynolds number is increased and then approaches an approximately constant value corresponding to the development of the recirculation zones.
