Deep-water oil spills such as the incident in the northern Gulf of Mexico 2010, produce turbulent oil plumes. Multiphase turbulent plumes under stratification are simulated to understand the dynamics of oil plume in oceanic environment. The evolution of the plume is strongly affected by the level of turbulent mixing during the rise of oil through the stratified water. The relative velocity due to the difference in density between oil and water causes slip of oil in water. The plume has been modeled as a two fluid mixture-model, which allows the use of one continuity and momentum equation for the oil-water mixture. The system of equations are non-dimensionalized by utilizing stratification and buoyancy parameters. The non-dimensional transport equations are solved using spectral element based Navier-Stokes solver NEK5000. Results from Direct Numerical Simulation are analyzed and compared with previous studies to understand the effect of oil slipping in turbulent plume under stratification.
