| 中文摘要 | Hydrodynamic coefficients induced by waves and currents are simulated for a stationary submerged circular cylinder in a twodimensional numerical wave-current tank. In present paper, based on the Reynolds averaged Navier-Stokes equations, a twodimensional numerical tank is developed to simulate the coaction processes. The computational vertical distributions of timeaverage velocity agree well with the experimental data, which indicates that the wave-current numerical tank has a good characteristic of wave-current combined flow. By using time histories of wave force, drift force are calculated. The computational results are also shown to be in good agreement with experimental and numerical results of other researchers. Simulated wave forces are employed to derive drag and inertia coefficients by using least-squares method. The coefficients induced by waves and wave-current flows are compared. The results indicate that the currents have a significant influence on the drag coefficients for submerged circular cylinder. |
