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 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 Acoustic Interaction
2008This is a survey of numerical methods to compute a particular fluid–solid interaction: the so called “elastoacoustic problem”. It concerns the determination of the motion of an elastic structure in contact with a compressible fluid. In this case displacements are small and, then, we can assume a linear response of the structure.We neglect gravity ...

Coupled Fluid-structure Interactions
2017In Fig. 3.1 we show a typical configuration of fluid-structure interactions. At time t = 0 the domain \(\varOmega \subset \mathbb{R}^{2}\) is split into a fluid-part \(\hat{\mathcal{F}}\) and a solid-part \(\hat{\mathcal{S}}\). This configuration is called the reference configuration and we assume that the system is at rest, i.e. v f = 0, p f = 0 and u
