Introduction. Very frequently the length of ambient waves λ is large compared to the dimension of floating bodies. For example the length of a wave with period T = 10 s is λ ≃ T 2 + T 2 2 ≃ 150 m. The beam of a ship with length L = 100 m can be 20 m as is the case for the diameter of the leg of an offshore platform.

WebThe inertial wave also exists for the small wind farm, but the amplitudes are approximately 4 times weaker and thus may be hardly observable in real wind farm flows that are more heterogeneous. Regarding turbulence intensity, the wake of the large wind farm has the same length as the wake of the small wind farm and is only a few kilometers long. Weblinearized long wave models in §2, we present the two-dimensional strongly nonlinear long wave model for the bottom velocity in §3, from which the third-order solitary wave …
