We consider the 2D liquid crystal systems, which consists of Navier-Stokes system coupled with wave maps or biharmonic wave maps, respectively. By logarithmic Sobolev inequalities, we obtain a blow-up criterion βˆ‡π‘‘,πœ•π‘‘π‘‘βˆˆπΏ1̇𝐡(0,𝑇;0∞,∞(ℝ2)) for the case with wave maps, and we prove the existence of a global-in-time strong solutions for the case with biharmonic wave maps.
