5. Objectives   Study fundamental oil-water interfacial phenomena (small-scale). Based on fundamental phenomena, develop models capable of predicting oil-water dispersion flow behavior (large-scale)   Include studies on coalescence and break-up, segregation and droplet size distribution   Validate developed models against current applications measurements
