Effects of Rotation on Three Dimensional Turbulence -- An Experimental Perspective
Dan Lathrop
Department of Physics, University of Maryland
|
Abstract: The
conceptual, analytical and numerical challenges for
three dimensional flows are well known. They
involve, at least, dealing with singularities in the
gradients, boundary layers, and the overwhelming
number of populated modes. If ones explores the
rotating case (as we have done experimentally)
things appear strikingly different. Inertial waves
modes, in a nonlinear context, appear to dominate
the energy scales. Sharp gradients also appear --
but not in locations traditionally worried about.
This talk will give some perspective from direct
observations in flows in water, liquid helium and
liquid sodium in parameter ranges not accessible by
other research techniques.
