论文摘要
我们使用直接数值模拟研究了由雷利 - 贝纳德对流驱动的旋转平面层发电机中速度和磁场之间的能量路径。动力学和磁能分为均值和湍流成分，以研究与大型和小规模发电机相关的生产，运输和耗散。这种基于能量平衡的表征揭示了Dynamos中大型和小规模磁场产生的不同机制，具体取决于速度场的性质以及在边界处施加的条件。
We investigate the energy pathways between the velocity and the magnetic fields in a rotating plane layer dynamo driven by Rayleigh-Bénard convection using direct numerical simulations. The kinetic and magnetic energies are divided into mean and turbulent components to study the production, transport, and dissipation associated with large and small-scale dynamos. This energy balance-based characterization reveals distinct mechanisms for large- and small-scale magnetic field generation in dynamos, depending on the nature of the velocity field and the conditions imposed at the boundaries.
