Elliptical instability
摘要：
In this review we describe the discovery and development ofunderstanding of the so-called elliptical instability. Thisis the name given to the linear instability mechanism that tendsto break up regions of elliptical streamlines in a rotatingflow. The instability is discussed in the three different contexts-anunbounded strained vortex, a localized strained vortex, anda triaxial ellipsoid-where it was originally discoveredand then rediscovered. These make it clear that the instabilityis one of parametric resonance where a normal mode, or pairof normal modes, of the undistorted rotating flow resonateswith the underlying strain field. The effects of additionalphysics on the instability process are examined before its nonlinearevolution is discussed. Various applications of the instabilityin nature are then reviewed.
