15 صفحه اولNumerical Approximation of Self-Consistent Vlasov Models for Low-Frequency Electromagnetic Phenomena
We present a new numerical method to solve the Vlasov-Darwin and Vlasov-Poisswell systems which are approximations of the Vlasov-Maxwell equation in the asymptotic limit of the infinite speed of light. These systems model low-frequency electromagnetic phenomena in plasmas, and thus “light waves” are somewhat supressed, which in turn allows the numerical discretization to dispense with the Coura...
متن کاملElectrostatic drift modes in a closed field line configuration
The stability of electrostatic drift waves in a closed field line configuration in collisionality regimes ranging from collisional to collisionless is compared. The maximum sustainable pressure gradient is found to be dependent on the ratio of the temperature and density gradients (h[d ln T/d ln n). The eigenmodes are seen to be flute-like. The stability boundary was found to be similar when bo...
متن کاملModelling Resistive Wall Modes with Self-consistent Inclusion of Drift Kinetic Resonances
We investigate the effect of drift kinetic damping on the resistive wall mode (RWM), due to the mode resonance with magnetic precession drifts and/or bounce motion of bulk plasma thermal particles. A self-consistent toroidal drift kinetic model is developed and incorporated into the MHD code MARS-F [Y.Q. Liu, et al., Phys. Plasmas 7, 3681 (2000)]. The new code (MARS-K) is used to study the RWM ...
