Gyrotropic Guiding-Center Fluid Theory for the Turbulent Heating of Magnetospheric Ions in Downward Birkeland Current Regions

摘要

A new fluid theory in the guiding-center and gyrotropic approximation derivable from the ensemble-averaged Vlasov-Maxwell equations that included the effect of wave-particle interactions for weakly turbulent, weakly inhomogeneous, nonuniformly magnetized plasma was recently given by Jasperse, Basu, Lund, and Bouhram Phys. Plasmas 13, 072903 (2006). In that theory, the particles are transported in one spatial dimension (the distances along the magnetic field) but the turbulence is two-dimensional. In this paper, which is intended as a sequel, the above theory is used for quasi-steady conditions...
