CFD Simulation of a real engine compressor including consideration of the deformation during operation

FSI-Simulation of a High Pressure Compressor

In order to analyse the stresses of HPC blades for repair purposes, a comprehensive, full detailed simulation of the entire compressor assembly has been carried out. The deformation of all the components has been considered using the Fluid-Structure-Interaction-Approach, so that the "hot" geometry could be analysed. Afterwards, additional FE-calculations using the modal superposition approach have been used to calculate the time-depending stress-field of the blades.
