Abstract:

Numerical experiments were conducted using an advanced high-resolution, non-hydrostatic 3D multi-phase model, incorporating capillary forces (ANSYS Fluent computational fluid dynamics software). These numerical simulations reproduced the spreading and contraction (due to the application of dispersant) of crude and machine oil on the surface of the water. These simulations were conducted from September to November 2015.

Purpose:

The dataset was developed to simulate the change in oil drop size over time. We conducted numerical experiments with crude and machine oil and we applied dispersants to the oil plumes.
