Direct numerical simulation of forced thermal convection in square ducts up to
We carry out direct numerical simulation (DNS) of flow in a turbulent square duct by focusing on heat transfer effects, considering the case of unit Prandtl number. Reynolds numbers up to $Re_\tau \approx 2000$ are considered which are much higher than in previous studies, and which yield clear scale separation …
