FLuid Imaging Experiments in Fluids (FLuX)

FLuX -- FLuid imaging eXperiments -- is a research group devoted to imaging fluids in the laboratory and field for visualization, estimation and inference. Our group started with a multiple Particle Tracker and has progressed to creating a Bayesian instrument for studying Geophysical Fluids-- the Planet-in-a-Bottle Project-- wherein numerical models are used to invert sparse measurements into full fields in order to better study them. This experiment also brought forward several issues in Data Assimilation, uncertainty quantification and sampling methodology. (See other field work.) Work in imaging bubbly flows and studying fluid interfaces are in progress. Much of this work is carried out at the Geophysical Fluids Laboratory and at the Naval Underwater Warfare Center (RI) and is of interest both to research and teaching.

The primary approach involves novel imaging techniques, computational photography, computational vision, and robotics to tackle low-level issues in fluid imaging. The Principals in this group are Sai Ravela (EAPS), John Marshall (EAPS) and Jesse Belden (NUWC).
