A Finite Element Solution of Fluid Structure Interaction Produced by Transient Flow Induced Vibration of Curved Pipe
High velocity pressurized fluids are often transported by pipes in a nuclear power plant (NPP). Pipes are often used under time-varying conditions due to valve operations. This can induce excitation problems. In the present work, dynamic analysis about the displacement of pipe wall based on finite element method of fluid structure interaction (FSI) induced excitation is introduced and applied to curved pipes. The fluid finite element model is based on flow velocity as the variable and stably maximum. The response of fluid filled curved pipe to valve open excitation has been studied. The vibrational displacement of the nodes selected in the model is discussed along the coordinate axis directions separately during the variable and stable stage of the flow velocity, and one curved pipe model is with both ends built-in and the other is fixed at one end.
