Numerical Simulation of Flow-induced Vibration of Tandem Circular Cylinders
摘要
Abstract
Numerical simulation is carried out for the flow-induced vibrations(FIV)of the elastically-mounted tandem cylinders in laminar flow by using immersed boundary method in the process of harvesting VIVACE ocean current energy (Vortex Induced Vibration Aquatic Clean Energy). The research results show the crosscurrent displacement of the upstream and downstream cylinders,vortex shedding frequency,lift-drag coefficient and the curve of the phase difference between lift force and displacement being affected by reduced flow velocity. In addition,analysis is made for the influence of cylinder’s spacing ratio on the hydrodynamic and FIV response characteristics of the tandem circular cylinders.关键词
