一类带磁场的双流体模型的整体弱解

Global weak solutions to some two-fluid models with magnetic field

Lin Ma, Boling Guo, Jie Shao

摘要:

证明了一类具有磁场的二流体系统的有限能量整体弱解的存在性,所得结果也适用于相应的二流体系统。本文的证明方法主要是受Novotnovel等人和Vasseur等人的启发。对于$academic~magnetic~ bi\text{-}fluid~ system$,我们主要讨论了理想气体压力定律的情形,新的内容是在不使用前提假设的情况下使证明更加明确,并去掉了Novotnovel等人的主要定理中一些不必要的条件。同时,对于结合Vasseur等人提出的压力定律的$real~magnetic~bi\text{-}fluid~system$,可以使用相同的证明方法。

英文摘要:

We prove the existence of global weak solutions with finite energy to some two-fluid systems with magnetic field and the results suit for corresponding two-fluid systems. The proof method is mainly inspired by Novotný et al. and Vasseur et al. For $academic~magnetic~ bi\text{-}fluid~ system$, we focus on the case of pressure law with ideal gases and the new ingredient is that we can make the proof more explicit without using the preposed hypotheses and remove some unnecessary conditions of the main theorem in Novotný et al. Meanwhile, the same proof method can be used for $real~magnetic~bi\text{-}fluid~system$ combined with pressure law proposed in Vasseur et al.
