摘要:
我们考虑建模向列型不可压缩液晶流的Beris-Edwards系统。该系统将描述流体速度的Navier-Stokes系统与描述液晶分子方向的Q-张量的抛物型反应-对流-扩散方程相耦合。本文通过考虑两个基本方面:特征值范围的保持和高Ericksen数极限下缺陷的动态出现,研究流对Q-张量动力学的影响。
英文摘要:
We consider the Beris-Edwards system modelling incompressible liquid crystal flows of nematic type. This couples a Navier-Stokes system for the fluid velocity with a parabolic reaction-convection-diffusion equation for the Q-tensors describing the direction of liquid crystal molecules. In this paper, we study the effect that the flow has on the dynamics of the Q-tensors, by considering two fundamental aspects: the preservation of eigenvalue-range and the dynamical emergence of defects in the limit of high Ericksen number
