Abstract
In this paper, we study the uniform regularity and vanishing viscosity limit for the compressible nematic liquid crystal flows in three-dimensional bounded domains. One establishes the uniform estimates for the solutions in a conormal Sobolev space and obtains the uniform estimates for the density and velocity in $W^{1,\infty}$. Then, it is shown that there exists a unique strong solution for the compressible nematic liquid crystal flows in a finite time interval which is independent of the viscosity coefficient. Based on the uniform estimates, we also obtain the convergence rate of the viscous solutions to the inviscid ones with a rate of convergence.
