Computational methods for fluid-structure analysis are surveyed. Emphasis is placed on semi-discretization methods, such as finite element and finite difference methods. Appropriate mesh descriptions and time integration procedures for various classes of problems are discussed.

Fluid structure interaction with large structural displacements
Computer Methods in Applied Mechanics and Engineering, 2001Calculations of viscous flows inside deformable structures can meet with difficulties when imposing kinematic compatibility conditions at the fluid-structure interface and updating the geometry of domain. Here the authors propose how to overcome these problems by considering fluid and structure as a common continuous medium in a fixed reference ...

Fluid-Structure Interaction of Propellers
2008The performance of a propeller is influenced by the wake of the ship, which results in an unsteady inflow to the propeller. Thus, the pressure on the propeller and its distribution as well as the resulting torque and thrust fluctuate during a revolution. These variations may evoke vibration of the propulsion system and a further transfer of the induced

Almost all problems solved in the previous chapters dealt with static fluid–structure scenarios where just the configuration of a solid structure at rest (or moving in the flow direction) determined the fluid flow field. Examples included internal flow through a conduit or external flow past submerged bodies.

Fluid-structure interaction and ADINA
Computers & Structures, 1983Abstract The theoretical basis of a fluid-structure interaction decoupling approximation for transient analysis of wave excited submerged structures is outlined. The approximation, called the Doubly Asymptotic Approximation (DAA) has been included in ADINA. Program modifications and additions are described.

There are many practical situations where the interaction between the dynamics of a structure and a surrounding fluid is of great importance. The most obvious is noise; noise is the propagation of acoustic energy through the fluid. The interaction can also influence the response of the structure itself; examples include dams, chimney stacks, ships ...

There are many kinds of fluid-structure interaction problems1,2,3. In this chapter only a few non-flow field problems, mainly fluid-shell dynamic interaction and fluid-solid impact will be discussed. The fluid-shell systems are used as models for sloshing and POGO (structure-propulsion coupling oscillation) in liquid rockets, floating lids Of oil tanks,

Fluid-Structure Interaction with Incompressible Fluids
2020These lecture notes cover a series of three two-hour lectures on fluid-structure interaction involving incompressible, viscous fluids, presented as the CIME Summer Workshop entitled “Progress in Mathematical Fluid Dynamics”, held in Cetraro, Italy, in June 2019.
