双曲线演化和流固耦合的变分方法

A variational approach to hyperbolic evolutions and fluid-structure interactions

Barbora Benešová, Malte Kampschulte, Sebastian Schwarzacher

摘要:

我们介绍了一个两个时间尺度的计划,它允许扩展的方法,最小化运动的双曲问题。该方法被用来显示弱解的存在性之间的非线性,粘弹性,$n$ -维大块固体的双曲型发展和不可压缩流体的($n$ -维)斯托克斯方程的$n\geq 2$的流体-结构相互作用问题。

英文摘要:

We introduce a two time-scale scheme which allows to extend the method of minimizing movements to hyperbolic problems. This method is used to show the existence of weak solutions to a fluid-structure interaction problem between a nonlinear, visco-elastic, $n$-dimensional bulk solid governed by a hyperbolic evolution and an incompressible fluid governed by the ($n$-dimensional) Navier-Stokes equations for $n\geq 2$.
