Tacoma Narrows Bridge under Wind Load
Fluid-structure interaction (FSI) is the interaction between some deformable
structure and the fluid around or inside it. Typical applications of FSI include
aeroelastic behavior of bridges, aircraft wings, wind turbine blades. One of the
most infamous examples is the Tacoma Narrows Bridge, which opened in July
1940 but collapsed due to aeroelastic flutter four months later.
The partitioned strategy for solving FSI allows reusing existing and well-tested
structure mechanics codes and fluid dynamics codes. During each time step, the
structure code and the fluid code will solve individually and exchange the fluid
load and the structure displacements at the interface.
In this work, the aerodynamic flutter of Tacoma Narrows Bridge will be modeled
and simulated. The software for the FSI simulation include EMPIRE, the coupling
tool; Carat++, the structure mechanics code; and OpenFOAM, the fluid dynamics
code.
The interest in C++ programming is required for this work.
