标题： 3D simulations of shear instabilities in magnetized flows

摘要： 我们展示了分层剪切层中磁流体力学Kelvin-Helmholtz不稳定性三维（3D）模拟的结果。磁场被认为是均匀的，并且与剪切流平行。我们描述了在一系列初始条件下流体流动和磁场的演化。特别是，我们研究了流体混合率如何依赖于理查森数和磁场强度。结果表明，磁场既能增强也能抑制混合。此外，我们还进行了二维（2D）模拟，并讨论了2D和3D结果之间的一些有趣差异。 显示英文摘要

摘要： We present results of three-dimensional (3D) simulations of the magnetohydrodynamic Kelvin-Helmholtz instability in a stratified shear layer. The magnetic field is taken to be uniform and parallel to the shear flow. We describe the evolution of the fluid flow and the magnetic field for a range of initial conditions. In particular, we investigate how the mixing rate of the fluid depends on the Richardson number and the magnetic field strength. It was found that the magnetic field can enhance as well as suppress mixing. Moreover, we have performed two-dimensional (2D) simulations and discuss some interesting differences between the 2D and 3D results.
