| Abstract: | The problem of the two-dimensional flow around a cylinder with elastic support is investigated using Discrete Vortex Method(DVM).The phenomenon of Vortex-Induced Vibration can be observed successfully in our simulation and the results have a very good agreement with the experiment results,proving that the Discrete Vortex Method(DVM)is simple and reliable for the investigation of the Vortex-Induced Vibration,especially having tremendous advantages for the simulation with high Reynolds number.The whole calcul... |
