多维全磁流体动力学 (MHD) 方程的低马赫数限制(其中考虑了热传导的影响)在密度和温度变化较小的经典解的框架内得到了严格证明。此外,我们表明,对于足够小的马赫数,可压缩 MHD 方程在不可压缩 MHD 方程的平滑解存在的时间间隔上允许平滑解。此外,还研究了具有小熵变的理想MHD方程的低马赫数极限。在两种情况下都获得了收敛率。
The low Mach number limit for the multi-dimensional full magnetohydrodynamic (MHD) equations, in which the effect of thermal conduction is taken into account, is rigorously justified within the framework of classical solutions with small density and temperature variations. Moreover, we show that for a sufficiently small Mach number, the compressible MHD equations admit a smooth solution on the time interval where the smooth solution of the incompressible MHD equations exists. In addition, the low Mach number limit for the ideal MHD equations with small entropy variation is also investigated. The convergence rates are obtained in both cases.
