Assessment of Tidal Stream Energy in the Bohai Strait Using A High Resolution Model
A high resolution tide current model of the Bohai Sea is built based on an unstructured grid,finite volume method ocean model(FVCOM).The results from the model agree well with previous studies and field data.The tidal waves in the Bohai Strait is described and the tidal stream enering is estimated based on the vertically averaged currents derived from the model.The results show that the tidal current is mainly rectilinear and the maximal value of the possible maximum velocity of the tidal current reaches 3.3 m/s at the west of the Laotieshan Cape.The sea area where the power density is larger than 100 W/m2 can reach to 515.9 km2 near the Laotieshan Cape.This is one order greater than that in the Dengzhou Channel,while the Dengzhou Channel is one oder larger than the rest channels.
