Space Plasma: The Plasma Physics of Non-Equilibrium Partially Ionized Gases

摘要本计画将探讨行星际介质中乱流的起源与动力学。 湍流将被纳入太阳风的平均场模型，并将研究湍流对冲击波的作用和冲击时粒子的加速。 还将研究湍流在宇宙射线调制中的作用。 湍流与太阳风平均场模型的耦合将通过在大尺度太阳风模型中引入湍流耗散源项来实现。 为了研究湍流在激波中的作用，将使用激波的耦合微观和宏观模型来推广Rankine-Hugoniot条件。 湍流对宇宙线调制的影响将通过在现有的宇宙线传输代码中添加湍流散射来实现。

AbstractThis project will examine the origin and dynamics of turbulence in the interplanetary medium. Turbulence will be incorporated into mean-field models of the solar wind and the role of turbulence on shock waves and the acceleration of particles at shocks will be investigated. The role of turbulence in the modulation of cosmic rays will also be investigated. The coupling of turbulence to the mean-field models of the solar wind will be accomplished by introducing source terms for the dissipation of turbulence into the large-scale solar wind model. To investigate the role of turbulence in shocks, coupled microscopic and macroscopic models of the shock waves will be used to generalize the Rankine-Hugoniot conditions. The influence of turbulence on cosmic ray modulation will be accomplished by adding turbulent scattering to existing cosmic ray transport codes.
