Nonlinear Electrostatic Ion-Acoustic-Like Instabilities in a System with Two Streaming Ion Components Moving in a Background Plasma
(Bentham open, 2008-11-26)
Finite amplitude Alfvén-cyclotron waves are believed to play an important role in coronal heating and
nonthermal properties of velocity distribution functions. These effects are thought to be due to parametrically ...
Nonlinear analysis of the shearing instability in granular gases
(2000)
It is known that a finite-size homogeneous granular fluid develops a hydrodynamiclike instability when dissipation crosses a threshold value. This instability is analyzed in terms of modified hydrodynamic equations: first, ...
Stabilization of the magnetosonic instability and destabilization of nonlinear electrostatic waves due to finite amplitude Alfv́n waves in a two ion-beam plasma
(2008)
It has been shown that a large amplitude Alfv́n wave can stabilize linear magnetosonic instabilities triggered by an ion beam. This phenomenon occurs for large amplitude waves above a threshold value. Here the effect of a ...
Effects of nonlinear left-hand circularly polarized waves supported by a proton beam on linear beam-plasma instabilities
(2005)
This paper studies the effect of nonlinear left-hand polarized waves supported by a proton beam on the linear circularly polarized instabilities driven by the same beam. It shows that the nonlinear wave can either stabilize ...
Linear and nonlinear electromagnetic and electrostatic instabilities in a plasma with two ion beams
(Blackwell Publishing Ltd, 2008)
Linear and nonlinear properties of a plasma system with a proton and an alpha-particle beam, are studied. It is shown that the presence of a second beam can change the linear and nonlinear stability thresholds of the ...
Nonlinear reduced-order modeling and bifurcation analysis of whirl flutter in a rotor-nacelle system
(2020-01-01)
Whirl flutter is an aeroelastic instability that can be affected by structural or/and aerodynamic nonlinearities. This instability may lead to potentially dangerous behaviors. In this study, a nonlinear reduced-order model ...
