Smooth Irrotational Flow in the Large to theEuler - Poisson System in
نویسنده
چکیده
A simple two-uid model to describe the dynamics of a plasma is the Euler-Poisson system, where the compressible electron uid interacts with its own electric eld against a constant charged ion background. The plasma frequency produced by the electric eld plays the role of`mass' term to the linearized system. Based on this`Klein-Gordon' eeect, we construct global smooth irrotational ows with small velocity for the electron uid.

Global Smooth Ion Dynamics in the Euler-poisson System
A fundamental two-fluid model for describing dynamics of a plasma is the Euler-Poisson system, in which compressible ion and electron fluids interact with their self-consistent electrostatic force. Global smooth electron dynamics were constructed in Guo [9] due to dispersive effect of the electric field. In this paper, we construct global smooth irrotational solutions with small amplitude for i...
متن کاملNon-neutral Global Solutions for the Electron Euler-poisson System in 3d
We prove that small smooth irrotational but charged perturbations of a constant background are global and go back to equilibrium in the 3D electron Euler-Poissson equation.
متن کاملTwo-fluid Electrokinetic Flow in a Circular Microchannel (RESEARCH NOTE)
The two-fluid flow is produced by the combined effects of electroosmotic force in a conducting liquid and pressure gradient force in a non-conducting liquid. The Poisson-Boltzmann and Navier-Stokes equations are solved analytically; and the effects of governing parameters are examined. Poiseuille number increases with increasing the parameters involved. In the absence of pressure gradient, the ...
متن کاملSpectral Dynamics of the Velocity Gradient Field in Restricted Flows
We study the velocity gradients of the fundamental Eulerian equation, ∂tu+ u · ∇u = F , which shows up in different contexts dictated by the different modeling of F ’s. To this end we utilize a basic description for the spectral dynamics of ∇u, expressed in terms of the (possibly complex) eigenvalues, λ = λ(∇u), which are governed by the Ricatti-like equation λt + u · ∇λ+ λ2 = 〈l,∇Fr〉. We focus...
متن کاملOn a class of nonlinear fractional Schrödinger-Poisson systems
In this paper, we are concerned with the following fractional Schrödinger-Poisson system: (−∆s)u + V (x)u + φu = m(x)|u|q−2|u|+ f(x,u), x ∈ Ω, (−∆t)φ = u2, x ∈ Ω, u = φ = 0, x ∈ ∂Ω, where s,t ∈ (0,1], 2t + 4s > 3, 1 < q < 2 and Ω is a bounded smooth domain of R3, and f(x,u) is linearly bounded in u at infinity. Under some assumptions on m, V and f we obtain the existence of non-trivial so...
