Investigation of the motion characteristics for a long flexible rotating pipe in flow by IDVM–FEM method

A long flexible rotating pipe in flow is investigated by using an improved discrete vortex method and finite element method. For the pipe without rotation, the lock-in phenomenon has been confirmed and discussed and the motion characteristics are illustrated at different flow velocities. For the pip...
