| Abstract: | The paper sum up many achienements in the computation of hydrodynamic coefficient on small diameter cylinders using the Morison Equation. The achienements on the the experimental studies, numerical simulation and hydrodynamic coefficient determination method are summarized with discussion about the signle cylinder and pile group. The effect of the current, current and wave, transverse force, veritical cylinder, incline cylinder, and roughness on hydrodynamic coefficient is elaborated. what’s more, the variation law of hydrodynamic coefficient under wave current condition is given. The method of solving the current hydrodynamic coefficients is summarized. Further work on the hydrodynamic coefficient of complex marine structures and other affecting factors is needed to develop efficient approaches. |
