LuFo V PRESTIGE: Interdisciplin­ary probabilistic analysis of compressor blades accounting for real geometry effects

The research project is founded within the scope of the joint research project
LuFo V: PRESTIGE. Here, the real geometry behaviour of a compressor and a
compressor stage respectively is investigated. For this purpose, the
manufactured geometry is captured by means of optical measurement
techniques. Subsequently, the geometric variability is described parametrically to
allow for multidisciplinary probabilistic analysis. In detail, the project covers the
following work packages:

• Investigation of methods for the parametric description of geometric variability of complex freeform geometry based on digital 3D models,
• Automated integration of geometric variability in CAD models based on highly accurate optical measurement data,
• Creation of “hot” real geometry of the fluid domain by means of coupled simulation of structure and fluid,
• Automated fluid meshing considering the geometric variability and accuracy requirements of CFD simulation,
• Probabilistic multidisciplinary simulation to predict the influence of geometric variability on aerodynamic performance.
