Introduction The flywheel energy storages are being intensively studied in mechanical engineering recently.

Introduction Since the 1980s, the fluid-structure interaction in various engineering areas has attracted broad academic attentions.
Theoretical and experimental results of the first 3 operational conditions indicate that they are consistent with each other, and that the results of the numerical model tally with that of the simplified model in engineering, errors are under 10%.
And no regularity is achieved, more attention should be paid to this issue in the engineering process.

Introduction Many water conservancy and civil engineering, such as piled wharf and pier wharf all are compose of different piles according to certain layouts.
Numerical models and physical models are the most commonly used simulation methods in engineering application at present.
Fig3 The calibration curve of the velocity 3 Determination of the roughness In tidal current numerical simulation of the engineering scheme, the pile wharf is simplified for gravity wharf and pier wall is simplified as fixed surrounding.
So when there exist piled wharf in the engineering scheme, considering pile influence is very necessary for the local flow field of dock front.
