This article describes the ORITRACK™mathematical model to simulate ORIMULSION™spills in water. ORIMULSION™is a low viscosity emulsion of heavy oil-in-water developed by the Venezuelan oil industry. This emulsion may be transported by pipelines and ships and burnt for electric energy generation in a very competitive manner. The model calculates the 2-D velocity field in the spill zone and simulates the emulsion dispersion in the 3-D space. Comparisons with analytical solution and field spill tests are presented. A Graphical User Interface (GUI) makes the model accessible to professionals with little computer training. ORITRACK™is an useful tool to study the ORIMULSION™trajectory and fate from instantaneous or continuous spill accidents in fresh or salt water.
