Numerical investigation of time-integration schemes applicable to fluid-structure interaction
In many civil engineering applications the interaction between fluid and structures represents a crucial aspect for analysis and proper design. The simulation of this phenomenon requires the application of high-fidelity numerical methods. In the current work, the fluid and structural equations both …

Alguns aspectos da interação fluido-estrutura em estruturas “off-shore”
The fluid-structure interaction problem is presented in a logical, basic and intuitive systematization, concerning offshore structures. The problem is identified, characterized and classified, as a whole; when particularized to structures in water, it is placed in a fisical and phenomenologic …

Aeroelastic optimization of thin flapping structure
… generated when a handheld fan is waved. This fluid-structure interaction problem is investigated through precision experiments, using an oscillating semi-circular elastic plate as a reduced analog model. The aerodynamic performance of the fans is systematically characterized for a variety of …

Vortex-induced vibrations of a non-linearly supported rigid cylinder
Vortex-Induced Vibrations (VIV) are a complex fluid-structure interaction problem.<br/>VIV are particularly strong for low-mass structures subject to a low damping, as<br/>encountered in the offshore industry, in which structures experiencing VIV can also<br/>be subject to strong structural …

Qualitative and Quantitative Study of the Flow Physics in the Vicinity of an Oscillating Plate in Viscous Fluids
In this thesis, we study the fluid-structure interaction problem of a submerged rigid plate undergoing harmonic oscillations in a still, Newtonian, viscous fluid. We conduct a comprehensive qualitative and quantitative analysis of the problem for a broad range of values of the parameters of …

Peridynamic modeling of fire damage in composites
… are important in terms of safety. This reality problem can be simplified as a thermal fluid-structure interaction problem in terms of mathematical modelling. The thermo-fluid model is used to simplify the physical properties of fire. The classical continuum mechanics has difficulty in predicting …

An Experimental Study of the Fluid- Structure Interactions of Water Entry of Compliant Structures
Water entry of compliant structures is a major area of interest within different fields of engineering. In the case of highly flexible panels, an application for this topic is on drag reduction due to shape reconfiguration of panels near the free surface to support further development of undulatory …

Aerodynamic and Electromechanical Design, Modeling and Implementation Of Piezocomposite Airfoils
… found in operating a relatively compliant, thin structure (desirable for piezoceramic actuators) in situations where there are relatively high external (aerodynamic) forces. Establishing an aeroelastic configuration that is stiff enough to prevent flutter and divergence, but compliant enough to …
