Physical problems are often characterised by a two-way interaction
of fluid flow and elastic structural deformation.
The fluid part will involve fully turbulent, incompressible flow in
many applications of engineering interest.
The present work is on residual-based variational multiscale modelling
of turbulence for such problems.
In this thesis, the residual-based large-eddy approach is stated in
an Arbitrary-Lagrangean-Eulerian setting.
It is studied thoroughly, especially with respect to the time-dependency
of the subgrid scales and the numerical dissipation of the model terms.
In addition, the influence of isogeometric representations and weak
boundary conditions is evaluated, and a successful application of the
approach in an example computation is provided.
