Future editions of this page will discuss research, but, for now, here are some samples: (Warning; these are all LARGE movie files.)

Fluid Mixing Processes
Our research on fluid mixing concentrates on the complex nonlinear dynamics associated with particle motion in unsteady flows. Cylinder Flow shows the vorticity field evolution for our unstructured, adaptive grid solver. Critical Points shows the evolution of critical points associated with the cylinder flow.
Particle Mixing Processes
We are interested in how finite particles (as opposed to fluid) points behave under mixing situations. Fluid Point-Like Partice Motion shows the behavior of particles with dissipation and inertial properties close to those of fluid points (i.e. small neutral density particles). Small Particle Motion illustrates the mixing behavior of very small particles that are less dense than the supporting fluid. Large Particle Motion is an example of the mixing behavior of large, heavy particles, i.e. ballistic motion.

Parallel Coordinates Visualization and Application
Parallel coodinates is a methodology to map multidimensional space to
two dimensional space. We are doing reserach in the application of this
viualization methodology to electric power production, distribution, and
control. In addition, we are applying the parallel coordinate paradigm
to multi-parameter optimization. See our CAIP
Center web site page.
