摘要: 采用一维磁流体力学模型和激波装配法,分析耀斑激波在行星际空间的传播特性和激波下游区的波动结构,并就激波装配法和激波捕捉法的模拟结果的精度和可靠性进行比较.Abstract: Using a one-dimensional MHD model and the shock fithng method (SFM), this paper discusses the propagation of flare-indutal shocks and the assodated wave structure downstream. It is shown that in the downstream region a rarefaction wave systo fonns, consishng of a fast rarefachon wave pair, and a reverse slow rarefaction wave and an entropy wave-like structure sandwiched in it. The same problem is also treated by the shock capturing method (SCM). It is concluded by comparison that the SCM cannot provide a reliable and a qualitahvely acceptible description of the propagation of flare-indued shocks in the interplanetary space, whereas the SFM seems to be the only prondsing choice.
