Coupled CFD-FEA simulation of long-span bridges
The design of long-span bridges is
dominated by considerations of aeroelastic instabilities.
In recent years we have
investigated the possibility
of using computational fluid dynamics (CFD)
fully-coupled to structural finite
element analysis (FEA) to simulate the
fluid-structure interaction around such structures. The first
aim is to verify or otherwise
such an approach.
I am now supervising Guido Morgenthal who is undertaking a PhD
on the use of computational fluid dynamics applied to bridges, focusing upon
the use of the Discrete Vortex Method and more traditional Finite Volume
CFD approaches to this aeroelastic problem. Guido's
research page should
contain plenty of information about how this work is progressing.
