3. Continuous improvement of numerical models

3.1 Simulation of fluid-structure interactions

The past decades have seen the development of numerical methods for the simulation of fluid/structure interactions in general, and there are numerous applications to nuclear capabilities, whether for academic studies (to understand the phenomena involved or refine risk assessment) or industrial studies (to demonstrate expected performance or validate design criteria).

• The numerical techniques available to engineers depend on the type of problem encountered. Generally speaking, there are two types of situation (figure 6...
