Abstract

Using the Finite-Volume Community Ocean Model (FVCOM) numerical model, considering the combination of parameterization of internal tidal dissipation and self-attraction and loading tide in the unstructured mesh model for the first time, a total of six tide-generation forces including M₂、S₂、N₂、K₁、O₁、Q₁ are established to drive the global forward tidal model. Based on the verification of the global tidal model results, we calculate and statistically estimate average density of the global tidal current energy, and show the tidal current energy distributions where there is greater tidal current energy in the world. The results show that there is a large tidal current energy belt with an area of nearly 33 000 $ {{\rm{k}}{\rm{m}}}^{2} $ and a maximum tidal current energy density of 1 100 $ {\rm{W}}/{{\rm{m}}}^{2} $ in the English Channel. The maximum tidal current energy density in the western side of Baffin Island in Canada exceeds 1 150 $ {\rm{W}}/{{\rm{m}}}^{2} $. The maximum tidal current energy density in the Cook Bay waters of Alaska is 500 $ {\rm{W}}/{{\rm{m}}}^{2} $. The tidal current energy belt at the entrance to the White Sea in Russia is large, where the maximum tidal current energy density reaches 500 $ {\rm{W}}/{{\rm{m}}}^{2} $. Australia's coastal tidal current energy belts have small area but large amount, and their tidal current energy density generally exceed 100 $ {\rm{W}}/{{\rm{m}}}^{2} $. In China's offshore waters, the tidal current energy density in the Hangzhou Bay waters of the Changjiang River Estuary and the north of Taipei reaches 100 $ {\rm{W}}/{{\rm{m}}}^{2} $.
