Revisiting linear gyrokinetics to recover ideal magnetohydrodynamics and missing finite Larmor radius effects
The linear gyrokinetics theory in the axisymmetric configuration is revisited. It is found that the conventional gyrokinetic theory needs to be repaired in order to recover the linear magnetohydrodynamics from the gyrokinetics and to obtain the finite Larmor radius effect on the magnetohydrodynamic modes in an ordering-consistent manner. Two key inclusions are: 1 the solution of the equilibrium...
متن کاملFinite Larmor Radius Effects and Quantum Chaos
Informed by insights from quantum chaos theory, three approaches for estimating finite-Larmor-radius (FLR) stabilization of ideal magnetohydrodynamic (MHD) instabilities are discussed: phase space criteria based on the Weyl formula, “pseudo-FLR” modifications of MHD to suppress large perpendicular wavenumbers, and inclusion of drift corrections to the dispersion relation. PACS numbers: 52.35.Bj...
متن کاملThe Finite Larmor Radius Approximation
The presence of a large external magnetic field in a plasma introduces an additional time-scale which is very constraining for the numerical simulation. Hence it is very useful to introduce averaged models which remove this time-scale. However, depending on other parameters of the plasma, different starting models for the asymptotic analysis may be considered. We introduce here a generic framew...
متن کاملNonlinear finite-Larmor-radius effects in reduced fluid models
The polarization magnetization effects associated with the dynamical reduction leading to the nonlinear gyrokinetic Vlasov–Maxwell equations are shown to introduce nonlinear finite-Larmor-radius FLR effects into a set of nonlinear reduced-fluid equations previously derived by the Lagrangian variational method A. J. Brizard, Phys. Plasmas 12, 092302 2005 . These intrinsically nonlinear FLR effec...
متن کاملFinite Larmor Radius Effects in Two-Dimensional Electrostatic Plasma Turbulence
Low frequency electrostatic turbulence in strongly magnetized, low @-plasmas, is studied in two spatial dimensions. In this limit the guiding center velocity in the direction perpendicular to a homogeneous magnetic field is approximated by the E x Bo/B,2-velocity. The electron Larmor radius can safely be set to zero for most relevant conditions, but the ion-dynamics are noticeably influenced by...
