Abstract
Accidental oil spill is one of the most critical problems associated with coastal protection and management. A recent corresponding incident is the Sanchi oil tanker collision in January 2018. Numerical simulation of oil drifting is widely utilized for prediction of oil spill area. However, the accuracy of these numerical simulations are often not sufficient due to presence of interfacial topological complexities, especially those associated with violent flows. In particular, precise prediction for initial mixing processes of oil and water would be of crucial importance.
This study aims at investigating the accuracy and potential applicability of an enhanced multi-phase ISPH method for simulation of oil-water mixing process. The method also incorporates a LES-based turbulence model, i.e. the SPS turbulence model, in order to take the effect of turbulence into account. The method's performance is investigated through a set of benchmark tests, namely, spreading oil slicks and continuous oil spill tests.
