流固耦合问题的整体和分区缩减基方法

A monolithic and a partitioned Reduced Basis Method for Fluid-Structure Interaction problems

Monica Nonino, Francesco Ballarin, Gianluigi Rozza

摘要:

这项工作的目的是提出一个概述约减基方法(RBM)与两种不同的方法相结合的流固耦合(FSI)问题,即整体和分区的方法。我们提供了两个减少程序的实施细节,然后我们将它们应用到相同的测试用例的兴趣。我们首先实现了一个减少技术,是基于一个整体的过程,我们解决了流体和固体的问题一次。然后,我们提出了另一种减少技术,是基于分区(或隔离)的程序:流体和固体的问题分别解决,然后耦合使用不动点策略。我们考虑的玩具问题是基于Turek-Hron基准测试用例,流体雷诺数Re = 100。

英文摘要:

The aim of this work is to present an overview about the combination of the Reduced Basis Method (RBM) with two different approaches for Fluid-Structure Interaction (FSI) problems, namely a monolithic and a partitioned approach. We provide the details of implementation of two reduction procedures, and we then apply them to the same test case of interest. We first implement a reduction technique that is based on a monolithic procedure where we solve the fluid and the solid problems all at once. We then present another reduction technique that is based on a partitioned (or segregated) procedure: the fluid and the solid problems are solved separately and then coupled using a fixed point strategy. The toy problem that we consider is based on the Turek-Hron benchmark test case, with a fluid Reynolds number Re = 100.
