Dynamics of Rotating Fluids

I study, both experimentally and theoretically, the oscillations of rotating fluids contained in ellipsoids and ellipsoidal shells. These studies have applications in rotating stars and planetary fluid cores. I also study elliptical instability in the Earth's fluid core, its effects on the Earth's free wobble, and as a possible source of energy for geodynamo. I use scalar representation of the field variables to solve the governing equations describing the dynamics of rotating fluids.

For simple experiments in rotating fluids have a look at the following experiment.
