Dr. Eckart Meiburg of the University of California at Santa Barbara gave a seminar Tuesday, April 8, on computational investigations of gravity and turbidity currents. He presented an overview of high-resolution, Navier-Stokes based on simulations of gravity and turbidity currents, focusing primarily on the standard lock-exchange configuration. The turbidity currents measured were driven by particles having negligible inertia and being much smaller than the smallest length scales of the buoyancy-induced fluid motion. Meiburg also discussed the differences between two- and three-dimensional gravity current dynamics; analyzed effects caused by stratification of the ambient; and showed some of the first results regarding the unsteady interaction of a gravity current with a submarine structure, such as a pipeline. The seminar was hosted by Dr. Steven Shaw.
