Three oil spill models were briefly reviewed. And based on the analysis of problems and defects existing in “Oil Particle” approach, a “TwoStep” method was put forward for oil spill simulation. The method divides oil spill movement into two steps: selfexpansion and turbulent expansion. The former step was handled by refinement of Fay’s equations, while the latter was handled by “Oil Particle” approach. Numerical experiment results show the “TwoStep” method can make up the shortcomings of “Oil Particle” approach and accords with the reality that spilled oil has different diffusion mechanism in the process of movement.
