Numerical Investigation on Flow-Induced Vibration Characteristics of Pipe-in-Pipe Auxiliary Pipe System

A pipe-in-pipe structure with a buoyancy damping layer is designed to reduce pipeline weight and suppress vortex-induced vibration. This structure avoids structural pre-stress problems caused by external buoys and mitigates severe local vibration. The four-degree-of-freedom motio...
