Аннотация

A two equation turbulence model has been used to predict heat transfer in a rotating square channel. The duct considered is smooth and the flow is radially outward. The predictions of local heat transfer for the leading and the trailing sides compare satisfactorily with the experimental data. Test cases with different Reynolds numbers and rotation numbers are considered. The expanded momentum equations include the Coriolis forces and the centrifugal buoyancy force. Standard and modified k-ε model predictions are presented. The empirical modifications for the Coriolis effect on the k and ε transport equations showed better agreement with the experimental data.
