Abstract

We consider in an infinite horizontal layer, the equations of the viscous compressible magnetohydrodynamic flows subject to the gravitational force. On the upper and lower planes of the layer, we consider homogeneous Dirichlet conditions on the velocity while a large constant vector field is prescribed on the magnetic field. The existence of the global strong solution with small initial data and its asymptotic behavior as time goes to infinity are established.

关于粘性可压缩 MHD 方程的全局和衰减解法
我们考虑在无限大水平层中,重力作用下粘性可压缩磁流体动力学流动的方程。在层的上下平面上,我们考虑速度上的齐次狄利克雷条件,而在磁场上规定了一个较大的恒定矢量场。建立了具有小初始数据的全局强解的存在性及其随时间趋于无穷时的渐近性。

期刊介绍: Studies in Applied Mathematics explores the interplay between mathematics and the applied disciplines. It publishes papers that advance the understanding of physical processes, or develop new mathematical techniques applicable to physical and real-world problems. Its main themes include (but are not limited to) nonlinear phenomena, mathematical modeling, integrable systems, asymptotic analysis, inverse problems, numerical analysis, dynamical systems, scientific computing and applications to areas such as fluid mechanics, mathematical biology, and optics.
