Uniform regularity and vanishing viscosity limit for the compressible nematic liquid crystal flows

Abstract

In this paper, we study the uniform regularity and vanishing viscosity limit for the compressible nematic liquid crystal flows in three dimensional bounded domain. It is shown that there exists a unique strong solution for the compressible nematic liquid crystal flows with boundary condition in a finite time interval which is independent of the viscosity coefficient. The solutions are uniform bounded in a conormal Sobolev space. Furthermore, we prove that the density and velocity are uniform bounded in W 1,∞ , and the director field is uniform bounded in W 3,∞ respectively. Based on these uniform estimates, one also obtains the convergence rate of the viscous solutions to the inviscid ones with a rate of convergence.

Low Mach number limit of global solutions to 3‐D compressible nematic liquid crystal flows with Dirichlet boundary condition

“…The local existence and uniqueness of classical solution were established by Ma,13 and the global existence of classical solutions to the Cauchy problem was shown in Li et al 14 with smooth initial data that has small energy. For more recent results about the compressible nematic liquid crystal flows, the readers can refer to previous works [15][16][17][18][19][20][21][22] and references therein.…”
