    To reduce friction in turbo machinery components, riblets are induced on compressor blades or pump impellers. Here, the grinding process enables a higher productivity in machining of riblet structures compared to knurling, ...
  • Böß, Volker; Grove, Thilo; Denkena, Berend; Mücke, A.; Nespor, D. (Amsterdam : Elsevier, 2016)
    While regenerating damaged components, e.g. compressor blades, the removal of excess weld material called re-contouring often determines the surface integrity including the residual stress state. A load-specific residual ...
  • Gilge, Philipp; Kellersmann, Andreas; Friedrichs, Jens; Seume, Jörg R. (London : SAGE Publications Ltd., 2019)
    Deterioration of axial compressors is in general a major concern in aircraft engine maintenance. Among other effects, roughness in high-pressure compressor reduces the pressure rise and thus efficiency, thereby increasing ...

    A major goal in the design of turbomachinery is the increase of efficiency. To attain this increase, the flow losses must be reduced. A substantial proportion of the losses is generated by skin friction between compressor ...
