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.
