自相似势流中不存在强规则反射

Non-existence of strong regular reflections in self-similar potential flow

Volker Elling

摘要:

我们考虑激波反射,它具有众所周知的局部非唯一性:反射激波可以是两种选择之一,称为弱和强。我们考虑的情况下,弱反射激波的整体解决方案的存在性已被证明,可压缩位流。如果也存在全局强激波解,那么势流将是不适定的。然而,我们证明了不存在的强冲击类似物在一个自然类的候选人。

英文摘要:

We consider shock reflection which has a well-known local non-uniqueness: the reflected shock can be either of two choices, called weak and strong. We consider cases where existence of a global solution with weak reflected shock has been proven, for compressible potential flow. If there was a global strong-shock solution as well, then potential flow would be ill-posed. However, we prove non-existence of strong-shock analogues in a natural class of candidates.
