HYDRO3D: Large Eddy Simulation (LES) of the near-field evolution of a subsea oil and gas plume

Hydro3D includes an Eulerian-Lagrangian algorithm for large-eddy simulation of bubble plume dynamics. The main numerical novelties consist on defining the gas-liquid coupling based on the bubble size to mesh resolution ratio where the interpolation between Eulerian and Lagrangian frameworks is achieved through the use of delta functions. The model's performance has been thoroughly validated for bubble plumes in tanks, cross flows and subjected to many different conditions.
