Abstract:

The interactions between fluid flows and immersed solid structures are nonlinear multi-physics phenomena that have applications to a wide range of scientific and engineering disciplines. Mathematically, such problems are described by systems of nonlinear PDEs linking the dynamics of the fluid and the structures. In this presentation, I will give a brief overview of representative numerical techniques currently available for computing fluid-structure interaction problems that involve incompressible flows, with a focus on methods of the immersed boundary type. In particular, I will highlight some recently developed immersed techniques which are capable of handling problems involving sophisticated structures described by detailed constitutive laws. Additionally, I will demonstrate the application of these methods through several non-trivial numerical examples, and will briefly mention a few challenges and open problems in this fast-growing computational field.
