Reduced magnetohydrodynamic equations with coupled Alfvén and sound wave dynamics
نویسندگان
چکیده
A set of reduced magnetohydrodynamic equations is described that is appropriate for the simulation of auroral Alfvén waves using curvilinear coordinates. These equations include the parallel electric field, ponderomotive force, diamagnetic drift effects, and gravity and rotation, but do not include the fast mode dynamics. The equations are formulated for multiple species, but quasineutrality is explicitly maintained. The equations have an exact conserved energy. © 2007 American Institute of Physics.

Sound Wave Propagation in Viscous Liquid-Filled Non-Rigid Carbon Nanotube with Finite Length
In this paper, numerical results obtained and explained from an exact formula in relation to sound pressure load due to the presence of liquid inside the finite-length non-rigid carbon nanotubes (CNTs), which is coupled with the dynamic equations of motion for the CNT. To demonstrate the accuracy of this work, the obtained formula has been compared to what has been used by other research...

Linear and nonlinear properties of moderate-toroidal-number (n) shear-Alfvén modes in tokamaks are investigated by using a hybrid MHD-particle simulation code, which solves the coupled set of MHD ~magnetohydrodynamic! equations for the electromagnetic fields and gyrocenter Vlasov equation for a population of energetic ions. The existence of unstable toroidal Alfvén eigenmodes ~TAE’s! and their ...
متن کاملAnalytical vibroacoustic modeling of an elastic Rayleigh beam using Green's function
The purpose of this article is to provide an analytical model of the vibroacoustic for an elastic beam submerged in low subsonic flows with mean velocities. In general, vibroacoustic modeling refers to the combined effects of sound propagation and mechanical vibration of the structure. Sound radiations from submerged structures are coupled with physical phenomena because the sound pressures act...

A computational study of resistive drift waves in the edge plasma of a stellarator with an helical magnetic axis is presented. Three coupled field equations, describing the collisional drift wave dynamics in the linear approximation, are solved as an initial-value problem along the magnetic field line. The magnetohydrodynamic equilibrium is obtained from a three-dimensional local equilibrium mo...
