本文研究液晶的可压缩流动。基于收敛稳定性原理,证明了当马赫数足够小时,可压缩液晶流的Cauchy问题在不可压缩液晶流存在的(有限)时间区间上存在唯一光滑解.进一步证明了当马赫数趋于零时,光滑解严格收敛于不可压方程的解,并得到了尖锐的收敛阶。
In this paper, we are concerned with the compressible flow of liquid crystals. Based on the convergence–stability principle, it is shown that, for the Mach number sufficiently small, the Cauchy problem of compressible liquid crystal flow has a unique smooth solution on the (finite) time interval where the incompressible liquid crystal flow exists. Furthermore, it is justified that, as the Mach number tends to zero, the smooth solutions converge rigorously to those of the incompressible equations, and the sharp convergence orders are also obtained.
