Numerical analysis of water entry under ocean currents with smoothed particle hydrodynamics method

The Physics of Fluids, 2023
Water entry is a fluid–structure interaction process closely related to the ocean environment. Repeated water entries take place when ships are sailing in an ocean environment, e.g., ocean currents, which greatly affect the ship's safety and stability in

Coverage path planning for multi-AUV considering ocean currents and sonar performance

Frontiers in Marine Science
Coverage path planning (CPP) for target search by autonomous unmanned vehicle (AUV) involves two crucial aspects: (1) the sonar performance of the AUV is sensitive to ocean environment, such as changes in terrain; and (2) the ocean currents significantly

Oil spill trajectory prediction with high-resolution ocean currents

Journal of operational oceanography. Publisher: The Institute of Marine Engineering, Science & Technology, 2020
Simulated ocean currents from ocean circulation models along with the surface winds are generally used to force an oil spill trajectory model. Ocean circulation is a key factor in determining the drift of the spilled marine pollutants. The simulations of
