Background<\/h3>\n

Oil droplets in the ocean will experience turbulence. Turbulence acts to break up these droplets.<\/p>\n

Goals<\/h3>\n

This project aims to measure the effect of turbulence and oil properties on turbulence dispersion rate, and to investigate the role of dispersants in creating micro-droplets.<\/p>\n

Facility<\/h3>\n

Spinning grids create isotropic turbulence in the center of the tank. Oil droplets are injected into the sample volume of size 17 x 17 x 70 mm3. High-speed inline digital holographic cinematography is used to visualize these droplets.<\/p>\n
