Abstract
The changes of developing turbulent flow characteristics in curved duct after adding a baffle were studied numerically at a body-fitted coordinate. A k-ε model was used to represent the turbulent characteristics. A curved duct with a rectangular cross-section was computed firstly. Two kinds of square ducts were studied: One was normal curved duct, the other was a duct with a baffle. The computational results show that the secondary flow in duct with a baffle is characterized by four vortices structure, compared with the duct without a baffle,the intensity of the secondary flows is reduced. This has much more significant meaning in engineering.
