Cavitation and bubble dynamics have a wide range of practical applications in a range of disciplines, including hydraulic, mechanical and naval engineering, oil exploration, clinical medicine and sonochemistry. However, this paper focuses on how a fundamental concept, the Kelvin impulse, can provide practical insights into engineering and industrial design problems. The pathway is provided thro...

The formation of an island circulation is investigated both theoretically and numerically in light of the dynamics of coastal Kelvin waves and Rossby waves. An island circulation is formed in three stages. First, the direction of the circulation is initiated by the coastal Kelvin wave; second, the transport of the circulation is established by the short Rossby wave dissipated against the easter...

Fourier optics is a powerful tool for the coherent manipulation of optical fields, for the spatial frequency analysis of images, and for the construction of real time correlators. One property that makes optics an exciting tool for frequency analysis is that, in free-space propogation of light, one can see the effects of lenses and filters on a light beam as the beam propogates through the syst...

Climate models and satellite observations both indicate that the total amount of water in the atmosphere will increase at a rate of 7% per kelvin of surface warming. However, the climate models predict that global precipitation will increase at a much slower rate of 1 to 3% per kelvin. A recent analysis of satellite observations does not support this prediction of a muted response of precipitat...

On electron kinetic scales, ions and electrons decouple, velocity shear on inertial length ∼de can trigger electromagnetic (EM) Kelvin–Helmholtz instability (EKHI). In this paper, we present an analytic study of EM EKHI in inviscid collisionless plasma with a step-function flow. We show that incompressible plasma, the ideal frozen-in condition E+ve×B/c=0 must be broken for to occur. flow, is re...
