Paper Title:
Vortex Induced Vibration Numerical Simulation of a Spring-Mounted Cylinder in Current
  Abstract

A 2D CFD numerical method based on loose coupling algorithms was adopted to simulate vortex induce vibration of a spring-mounted cylinder. As the accuracy and reliability were focused, the effect analysis of time-step was applied to three typical reduced velocities, which was represented initial branch, upper branch and lower branch respectively. Under the effective courant number, there exist a time-step which would lead to the highest efficiency and the best match for experiment. Because of the limit of RANS method, the predicted vibration amplitude at the upper branch would be lower than experiment value, while the phase angle is sensitive to time step.
