Abstract：Heat transfer characteristic of a vibrating cylinder in two-dimensional fluid flow was numerically investigated by the dynamic meshing and UDF programming technology via Fluent CFD software. The influence of flow velocity and the vibrating direction of cylinder on heat transfer were discussed. The numerical results show that, comparing with the still cylinder heat transfer, when the flow velocity is well below the maximum cylinder vibrating speed, the cylinder vibration has a significant influence on heat transfer enhancement, and the influence was reduced with the increase of the flow velocity, when the flow velocity is 4 times as the max cylinder vibrating speed, increase of the average Nu was only 1.2%. Study on Vibrating heat transfer characteristic of cylinder vibrating along different directions at the same flow velocity shows that the vibrating direction has little influence on heat transfer enhancement.
