Oil droplets model can calculate droplet sizes and their distribution when oil is released as a jet from an underwater release or near surface spill from a ship that is subjected to ocean waves. This is not an empirical model and differs from most other models available for the purposes. Oil droplets was developed from ground up over 8 years. It is a phenomenological model that uses population balance concept, with droplet physics and fluid mechanics integrated. The time and special evolution of droplet size distribution is modeled based on droplet breakup and coalescence concepts. Hence the model is expected to work in a wide range of release conditions. The model results have been extensively tested with the available field and laboratory data. The results from comparisons are very good for mm size droplets as well as small micrometer size droplets.

Complete details of the model formulation, test runs to compare with experimental data, and test scenario simulations have been presented in major hydraulic engineering conferences and journals as research papers. The comparisons are very good. Others have adopted the techniques.
