Non-physical momentum sources in slab geometry gyrokinetics

Felix I Parra, Peter J Catto2010年Plasma Physics and Controlled FusionIF 2.2出版社

We investigate momentum transport in the Hamiltonian electrostatic gyrokinetic formulation of Dubin et al (1983 Phys. Fluids26 3524). We prove that the long wavelength electric field obtained from the gyrokinetic quasineutrality introduces a non-physical momentum source in the low flow ordering.

我々は、Dubinら(1983 Phys. Fluids 26 3524)のハミルトン形式の静電ジャイロ運動論的定式化における運動量輸送を調査する。ジャイロ運動論的準中性条件から得られる長波長電場が、低流速オーダーにおいて非物理的な運動量源を導入することを証明する。
