Turbulence

Turbulence is the erratic flow of a gas or a liquid. It is all around us, and understanding it is of great practical importance for industrial processes, for transportation, and for understanding our environment and climate. Turbulence is an unsolved problem of classical physics: no closed equation exists that can predict the statistical properties of the erratic flow.  Although the equation of motion of the flow is well established, we do not know how to use it for the prediction of turbulence. Our research covers many aspects of turbulence; it is a combination of  experiments,  numerical simulations, and theory.  Although the research is aimed at fundamental issues, it has a variety of applications for geophysical and industrial flow situations.
