Vortex Rossby waves on smooth circular vortices Part I. Theory
A complete theory of the linear initial-value problem for Rossby waves on a class of smooth circular vortices in both f-plane and polar-region geometries is presented in the limit of small and large Rossby deformation radius. Although restricted to the interior region of barotropically stable circular vortices possessing a single extrema in tangential wind, the theory covers all azimuthal waven...

15 صفحه اولVortex Rossby waves on smooth circular vortices Part II. Idealized numerical experiments for tropical cyclone and polar vortex interiors
Idealized linear and nonlinear numerical experiments are carried out to test the predictions of the theory developed in Brunet and Montgomery [Vortex Rossby Waves on Smooth Circular Vortices Part I: Theory (pages 153–177, this issue)]. For a monopolar tropical cyclone-like vortex whose strength lies between a tropical depression and tropical storm, linear theory remains uniformly valid in time ...
متن کاملShear Layer Vortices and Longitudinal Vortices in the Near Wake of a Circular Cylinder
J. Soria Department of Mechanical Engineering, Monash University, Clayton, Australia • Results are presented on (1) the shear layer vortices developing in the free shear layers located between the separation point and the first shed Strouhal vortex of a circular cylinder and (2) the longitudinal vortices developing in the braid region of the Strouhal vortices in the wake. Evidence based on flow...
متن کاملFundamental Studies of Vortices Induced by a Vortex-generator for Automotive Applications
For automotive applications, passive flow control devices can be used to reduce, delay or prevent flow separation. This study explores the nature of vortex generation and behaviour, numerically and experimentally, for a simple geometry at a Reynolds Number (Rex) of 5×10 5 and 1.945×10 6 . The setup comprised a triangular vane vortex-generator mounted on a shallow ramp referenced from literature...
