Transient Waves Produced by a Moving Pressure Distribution
This paper provides a theoretical description of the 3-dimensional flow produced by a surface pressure distribution moving in a channel at speeds such that the Froude number based on depth is near 1. The transient flow begins in a fully 3-dimensional manner, then focuses away from the distribution, due to the side walls, into predominantly 2-dimensional "solitary" or "cnoidal" waves. Two sets o...
متن کاملMagneto-hydrodynamic Stirrer for Stationary and Moving Fluids
A magneto-hydrodynamic (MHD) stirrer that exhibits chaotic advection is designed, modeled, and tested. The stirrer can operate as a stand-alone component or it can be incorporated into a MHD-controlled network. The stirrer consists of a conduit equipped with individually controlled electrodes positioned along its opposing walls. The conduit is filled with an electrolyte solution and positioned ...
متن کاملStudies on Magneto-hydrodynamic Waves and Other Anisotropic Wave Motions
There are two separate but closely interwoven strands of argument in this paper; one mainly mathematical, and one mainly physical. The mathematical strand begins with a method of asymptotically evaluating Fourier integrals in many dimensions, for large values of their arguments. This is used to investigate partial differential equations in four variables, x, y, z and t , which are linear with c...
متن کاملPropagating magneto-hydrodynamic waves in a cooling homogenous coronal plasma
Aims. We present an investigation into how the cooling of the background plasma influences the propagation of slow and fast MHD wave modes supported by an unbounded, homogenous plasma. Previous investigations have suggested that the cooling of the plasma and a reduction in density could lead to the damping of fast magneto-acoustic oscillations. We aim to investigate whether cooling of the backg...
متن کاملSpontaneous generation of spiral waves by a hydrodynamic instability
The coiling of a thin filament of viscous fluid falling onto a surface is a common and easily reproducible hydrodynamic instability. Here we report for the first time that this instability can generate regular spiral patterns, in which air bubbles are trapped in the coil and then advected horizontally by the fluid spreading on the surface. We present a simple model that explains how these beaut...
