In the present study (Brethouwer, 2018, 2019) heat transfer in rotating turbulent channel flow is investigated through DNS at moderate Reynolds numbers. It is shown that rotation has a large influence on the mean temperature profiles and heat fluxes and also on the structure of the temperature field. The turbulent Prandtl number on the unstable side is strongly reduced by rotation, implying that the Reynolds analogy for momentum-heat transfer does not necessarily hold for rotating turbulent channel flow.
