Controversy on a dispersion relation for MHD waves
Abstract Kumar et al. (2006) obtained a fifth order polynomial in ω for the dispersion relation and pointed out that the calculations preformed by Porter et al. (1994) and by Dwivedi & Pandey (2003) seem to be in error, as they obtained a sixth order polynomial. The energy equation of Dwivedi & Pandey (2003) was dimensionally wrong. Dwivedi & Pandey (2006) corrected the energy equation and stil...
متن کاملDispersion Relation for Alfvén Waves in a Viscous, Diffusive Plasma
Propagation of Alfvén waves in the solar plasma has been a topic of scientific interest for a long time. We have derived a dispersion relation ω4 + ω2[(ν2 + η2)k4 − v2 A k2] + iω(ν + η)v2 A k4 + (νηv2 A k6 + ν2η2k8) = 0 for shear Alfvén waves in a viscous and diffusive plasma. The MHD equations for viscous and diffusive plasma are ρ ∂ → v ∂t + ρ( → v .∇) →v= 1 μ (∇× → B)× → B +ρν∇ → v Momentum ...
متن کاملExperimental Determination of the Dispersion Relation for Spiral Waves.
We have experimentally measured the dispersion relation of spiral waves in the BelousovZhabotinsky reaction in an open spatial reactor, for different concentrations. Appropriate rescaling permits the collapse of all data onto a single line. From this, we infer an analytic form for the dispersion relation, which only depends on two physical quantities. In particular, this relation implies that t...
متن کاملOn the Analysis of Dispersion Relation of Spatially Shoaling Waves
As waves propagate into nearshore waters, the wave dispersive relation is significantly affected by the nonlinear dynamics of the shoaling process (Herbers et al. 2002). This could have important effects to the interpretation and application of remote sensing results of shallow water waves (Stockdon and Holman, 2000). Many field studies are carried out based on temporally measured wave data to ...
متن کاملDispersion relation for water waves with non-constant vorticity
We derive the dispersion relation for linearized small-amplitude gravity waves for various choices of non-constant vorticity. To the best of our knowledge, this relation is only known explicitly in the case of constant vorticity. We provide a wide range of examples including polynomial, exponential, trigonometric and hyperbolic vorticity functions.
