Xianpeng Hu, Dehua Wang

摘要:

本文考虑三维可压缩磁流体动力学等熵流方程。研究了有界区域上一类具有大数据量的初边值问题。对于绝热指数$γ>\frac32$和常粘性系数,通过三层近似、能量估计和弱收敛性,得到了整体弱解的存在性和大时间行为.

英文摘要:

The three-dimensional equations of compressible magnetohydrodynamic isentropic flows are considered. An initial-boundary value problem is studied in a bounded domain with large data. The existence and large-time behavior of global weak solutions are established through a three-level approximation, energy estimates, and weak convergence for the adiabatic exponent $γ>\frac32$ and constant viscosity coefficients.
