论文摘要
我们考虑了化学反应以及粘度，扩散，热扩散和热导率效应，为非荧光多组分磁化电荷相对论混合物制定了流体动力方程。所得的方程式具有相当简单的形式，可以很容易地应用，例如，用于研究中子星的磁热演化。我们还建立了形式主义与文献中已知的结果之间的联系，并通过微观理论计算出的动量传递速率来表达现象学扩散系数。
We formulate hydrodynamic equations for nonsuperfluid multicomponent magnetized charged relativistic mixtures, taking into account chemical reactions as well as viscosity, diffusion, thermodiffusion, and thermal conductivity effects. The resulting equations have a rather simple form and can be readily applied, e.g., for studying magnetothermal evolution of neutron stars. We also establish a link between our formalism and the results known in the literature, and express the phenomenological diffusion coefficients through momentum transfer rates which are calculated from microscopic theory.
