Focusing of an inertia - gravity wave packet by a baroclinic shear flow
We investigate the interaction of a small-amplitude internal gravity wave packet in a rotating fluid with a baroclinic shear flow. Ray equations and three-dimensional direct numerical simulations of the Boussinesq equations are solved for this purpose. The shear flow has a simple structure and depends separately on the vertical and horizontal coordinates. We focus on the situation where the int...

متن کاملShear wave focusing for three-dimensional sonoelastography.
A new vibration scheme is shown to provide localized vibration fields for three-dimensional sonoelastography imaging. The theoretical vibration distributions of double strip loads vibrating normally to the surface of a semi-infinite elastic space are calculated. A localization or focusing of shear waves inbetween the double-strip loads is predicted. Experimentally, two parallel rigid rectangula...
متن کاملInstability Associated Baroclinic Critical Layers in Rotating Stratified Shear Flow
The notion of over-reflection has been used to rationalize the linear instability of shear flows that are directed and sheared in a horizontal plane but stratified and subject to rotation in the vertical. In the linear stability analysis of these types of flows, two types of critical levels may appear that translate to singular points in the corresponding differential eigenvalue problem. The fi...
متن کاملDiffusing - wave spectroscopy in a shear flow
We present a new technique for measuring velocity gradients for laminar shear flow, using dynamic light scattering in the strongly multiple-scattering regime. We derive temporal autocorrelation functions for multiply scattered light, taking into account particle displacements arising from deterministic shear flow and random Brownian motion. The laminar shear flow and Brownian motion are charact...
