Stability Diagrams for Landau Damping
Coherent modes which are present when there is no incoherent tune spread may be absent when such a spread exists. Such modes are “Landau damped.” There is instead an incoherent spectrum, a continuum of an infinite number of frequencies, which will decohere (filament), thus not leading to collective instabilities. A stability diagram indicates when Landau damping will be effective. It divides th...
متن کاملResearch Article Modeling of Coupled Roll and Yaw Damping ofa Floating Body in Waves
A mathematical model is described to investigate the damping moment of weakly nonlinear roll and yaw motions of a floating body in time domain under the action of sinusoidal waves. The mathematical formulation for added mass moment of inertia and damping is presented by approximating time-dependent coefficients and forcing moments when small distortion holds. Using perturbation technique, we ob...
متن کاملAsymptotic Stability of the Wave Equation on Compact Surfaces and Locally Distributed Damping - a Sharp Result
This paper is concerned with the study of the wave equation on compact surfaces and locally distributed damping, described by utt −∆Mu+ a(x) g(ut) = 0 on M× ]0,∞[ , where M ⊂ R is a smooth oriented embedded compact surface without boundary. Denoting by g the Riemannian metric induced on M by R, we prove that for each ǫ > 0, there exist an open subset V ⊂ M and a smooth function f : M → R such t...
متن کاملDamping Characteristics of Viscoelastic Damping Structure under Coupled Condition
Temperature has an influence on damping characteristics of the viscoelastic damping structure. The change of the damping characteristics of the structure under the cycle load is a dynamic and coupled process. The hyperelastic-viscoelastic model was used to describe nonlinear deformation and viscoelasticity simultaneously. The temperature distribution and change of the damping characteristics un...
متن کاملDamping of visco-resistive Alfven waves in solar spicules
Interaction of Alfven waves with plasma inhomogeneity generates phase mixing which can cause the dissipation of Alfven waves. We investigated the dissipation of standing Alfven waves due to phase mixing at the presence of steady flow and sheared magnetic field in solar spicules. Moreover, the transition region between chromosphere and corona was considered. Our numerical simulation showed that ...
