Abstract :
This paper presents a three- dimensional numerical model for prediction of themovement of oil slicks from a spill accident in the Strait of Singapore. The results ofthis model are compared with the results of the model which was run by Chao et al.This model has previously been developed for prediction of movement of gascondensates from spill accidents in the Assalouyeh marine Oil and Gas region andhas achieved good results. The model is simulated based on the solution of theNavier-Stokes and the continuity equations. For the solution of advection term anupwind weighted multidimensional positive definite advection transport algorithm(MPDATA) used. This algorithm uses an explicit finite difference scheme with ananti-diffusive velocity for equilibrium diffusion. Comparison of the results of the twomodels showed good consistency that is considered for the introduced model as areliable verification.
