Important results from the project
Main objectives of final phase of ADiSS project were to numerically and experimentally investigate influence of surface roughness and leading edge erosion on aeroelastic response of compressor blades, in particular when compressor operate at off-design operating point with local separated flow. The objective was fully achieved within project timeframe. Results demonstrate that surface roughness and leading edge erosion can have a noticeable influence on the aeroelastic response of the blades.
Expected long term effects
The outcome of the numerical simulations and measurements carried out in the project has contributed to an improved understanding of the basic phenomena that lead to or affect blade vibrations, as well as how this is affected by the surface roughness and leading edge erosion of the blades. This in turn, leads to improved analysis methods that can predict the occurrence of potentially dangerous blade vibrations under long-term and adverse operating conditions.
Approach and implementation
The project included both numerical calculations and experimental measurement campaigns. The doctoral student in project successfully completed his doctoral studies and defended in early June 2025. Project results have been reported in several scientific publications. Collaboration and knowledge transfer between GKN and KTH have worked very well, with regular follow-up meetings between the project participants throughout the project period, which has been crucial to the success of the project.
