Dr. Tim Colonius, Ph.D.
Tim Colonius, Associate Professor of Mechanical Engineering, California Institute of Technology (Ph.D., Stanford University, 1994), has research interests in the areas of computational fluid dynamics, aeroacoustics, turbulence, cavitation, and other complex unsteady flow phenomena. He has developed innovative, high-order, accurate numerical methods and robust and accurate nonreflecting boundary conditions that allow direct computation of unsteady flows together with their generated sound fields. He has performed simulations for a variety of flows important for application, including vortices, vortex rings, mixing layers, jets, and flow over open cavities. He was awarded the National Science Foundation (NSF) CAREER award for investigations of sound generation by turbulent jets and the International Union of Theoretical and Applied Mechanics (IUTAM) Bureau Prize for work on the basic instability mechanisms for open-cavity flows. His aeroacoustic research at Caltech has been supported by NSF, Air Force Office of Scientific Research, and the Defense Advanced Research Projects Agency. Dr. Colonius' work also includes the development of numerical methods for simulation of unsteady, bubbly, cavitating flows (supported by NSF), such as those that occur during cloud cavitation on propellers. Recent applications also include shockwave lithotripsy, supported by the National Institutes of Health (NIH).
