论文摘要
我们提出了一组快速简便的特征变量，用于用于磁性流体动力学（MHD）的冲击捕获方案的高阶重建。数值实验表明，使用近似特征变量的重建比使用保守或原始变量的重建更健壮，而其计算效率则相当。与MHD的完整特征变量相比，近似特征变量很简单，并且可以是重建变量的实际选择。
We propose a set of quick and easy approximate characteristic variables for higher-order reconstructions of shock capturing schemes for magnetohydrodynamics (MHD). Numerical experiments suggest that the reconstructions using the approximate characteristic variables are more robust than those using the conservative or primitive variables, while their computational efficiencies are comparable. The approximate characteristic variables are simple compared to the full characteristic variables for MHD, and can be a practical choice of reconstruction variables.
