一类流体动力系统的强解、全局正则性和稳定性

Strong solutions, global regularity and stability of a hydrodynamic system modeling vesicle and fluid interactions

Hao Wu, Xiang Xu

摘要:

在本文中,我们研究了一个流体动力学系统模拟囊泡膜的变形在不可压缩的粘性流体。该系统由Navier-斯托克斯方程和四阶相场方程耦合而成。在三维情形下,我们证明了任意初值下局部强解的存在唯一性以及在大粘性假设下的整体强解.我们还建立了局部光滑解的速度正则性准则。最后,我们研究了系统在弹性弯曲能局部极小点附近的稳定性。

英文摘要:

In this paper, we study a hydrodynamic system modeling the deformation of vesicle membranes in incompressible viscous fluids. The system consists of the Navier-Stokes equations coupled with a fourth order phase-field equation. In the three dimensional case, we prove the existence/uniqueness of local strong solutions for arbitrary initial data as well as global strong solutions under the large viscosity assumption. We also establish some regularity criteria in terms of the velocity for local smooth solutions. Finally, we investigate the stability of the system near local minimizers of the elastic bending energy.
