Abstract: 

This study considers oil trajectory and fate models in the Persian Gulf, which have been studied in Iran and other countries. The governing equations and the main physical parameters are determined in processes affecting an oil slick. Schmidt and Richardson numbers are used in mass transfer coefficient for evaporation and vertical diffusion coefficient, respectively. The main governing equations of the movement of the oil slick are Navier-Stokes equation, continuity equation and concentration transport equation. The effective source term (mass balance), which includes the evaporation, dissolution, and vertical dispersion, as well as the shoreline and bed deposition and also vertical and horizontal diffusion coefficients are important factors in the concentration transport equation.
Based on studies, an ideal two-dimensional trajectory and fate model simulates the movement of the oil slick. The characteristic of an ideal three-dimensional oil fate model simulates the distribution of oil particle concentration in the water column. This model is proposed for the prediction of oil spill movement in the Persian Gulf. The model has been run for the region between the Khark Island and the Bushehr Port. The results show consistency with other similar studies.
