一类趋化性-Navier-Stokes方程组自由边界值问题的整体解

Global solutions to the free boundary value problem of a chemotaxis-Navier-Stokes system

Qianqian Hou

摘要:

在本文中,我们研究了有限深度的三维移动区域上的趋化性Navier Stokes方程组的整体可解性,该区域下有刚性平底,上有自由表面。在实验和数值模拟中,我们用与边界描述相匹配的边界条件来完成系统,在一个恒定状态$(0,\hat{c},\mathbf{0})$附近建立了整体解的存在性和唯一性,其中$\hat{c}$是自由表面上氧的饱和值.据我们所知,这是第一个分析工作的适定性的趋化性Navier-Stokes系统上的时间依赖域。

英文摘要:

In this paper, we investigate the global solvability of the chemotaxis-Navier-Stokes system on a three-dimensional moving domain of finite depth, bounded below by a rigid flat bottom and bounded above by the free surface. Completing the system with boundary conditions that match the boundary descriptions in the experiments and numerical simulations, we establish the global existence and uniqueness of solutions near a constant state $(0,\hat{c},\mathbf{0})$, where $\hat{c}$ is the saturation value of the oxygen on the free surface. To the best of our knowledge, this is the first analytical work for the well-posedness of chemotaxis-Navier-Stokes system on a time-dependent domain.
