Abstract
In this study a fully coupled aeroelasticity simulation in the time domain of a low pressure turbine (LPT) is demon- strated. The transformation from the unloaded blade geometry to the loaded (consisting of the steady pressure and centrifugal forces) geometry is considered in the initialisation of the cou- pled solver. The fluid-structure interaction (FSI) solver consists of the flow solver TRACE and the structural solver CalculiX. After validation of the FSI solver its performance and behav- ior is evaluated in terms of simulation time and capabilities for limit cycle oscillations.
