Thermodynamical Consistent Modeling and Analysis of Nematic Liquid Crystal Flows

Matthias Hieber, Jan Pruess

摘要:

本文在非等温条件下重新考虑了一般的Ericksen-Leslie系统,目的是为了得到热力学一致的模型。非等温模型,然后分析研究。一个相当完整的动力学理论是通过分析这些系统作为准线性抛物型发展方程在$L^p-L^q$设置。首先证明了该方程存在唯一的局部强解。然后,它表明,该解决方案扩展到一个全球性的强解提供的初始数据是接近平衡或解决方案最终有界的基础状态空间的自然规范。在这些情况下,解指数收敛到自然状态流形中的平衡点。

英文摘要:

The general Ericksen-Leslie system for the flow of nematic liquid crystals is reconsidered in the non-isothermal case aiming for thermodynamically consistent models. The non-isothermal model is then investigated analytically. A fairly complete dynamic theory is developed by analyzing these systems as quasilinear parabolic evolution equations in an $L^p-L^q$-setting. First, the existence of a unique, local strong solution is proved. It is then shown that this solution extends to a global strong solution provided the initial data are close to an equilibrium or the solution is eventually bounded in the natural norm of the underlying state space. In these cases, the solution converges exponentially to an equilibrium in the natural state manifold.
