Abstract: Recent results demonstrating that librational forcing can drive intense motions through the elliptical instability are presented. We recover the libration induced base flow, a time-averaged zonal flow, and discuss the properties of the libration-driven elliptical instability in non-axisymmetric ellipsoidal geometry. Excitation of bulk-filling turbulence by this forcing provides a mechanism for transferring rotational energy into turbulent fluid motions and thus may play an important role in the thermal evolution and magnetohydrodynamics of rotating bodies.
