文摘
- •
The movement of oil droplets was simulated by assuming an irregular sea state following a JONSWAP spectrum.
- •
A technique known as Wheeler stretching was adopted to model the movement of particles under the moving water surface.
- •
Small eddy diffusivities that decrease rapidly with depth generated the largest horizontal spreading of the plume.
- •
Neglecting the buoyancy of oil would overestimate the spreading of buoyant oils.
