Abstract:
In order to reasonably simulate tidal currents around small structures such as piles in a large-scale model domain, a 2-D hydrodynamic integrated model for Bohai Sea is established with the finite element method. The grid can be discretionarily refined as a non-structure triangle or quadrilateral so that piers can be treated as one or several impermeable elements with an area of 20 to 30 km2 in a model domain over 85 700 km2.The computational results of tidal levels and horizontal velocities are in good agreement with the field data.Based on the computed results by the model, the layout of an open 105 DWT liquefied natural gas(LNG)terminal in Caofeidian, Bohai Sea is effectively and reasonably optimized.It can be concluded that the model is suitable and reasonable for direct simulation of tidal currents around small structures in projects.
