1. Numerical methods for calculating a structure coupled with a flowing fluid

1.1 Modeling assumptions

In this section, we focus on numerical methods for solving a coupled fluid/structure problem in the case of a flowing fluid. The physical phenomena involved in the interaction of fluid and structure are more complex than in the case of stagnant fluid, and involve a variety of coupling mechanisms . Additional difficulties are posed by the non-linear behavior of the fluid (and possibly the structure), so that the whole range of problems posed by fluid/structure interaction in the case of fluid flow – both in terms of mathematical...
