    • Effect of Vaneless Diffuser Width on the Overall Performance of a Centrifugal Compressor 

      Jaatinen, Ahti; Grönman, Aki; Turunen-Saaresti, Teemu; Röyttä, Pekka (Sage Journals, 2011)
      Three vaneless diffuser designs, varying in diffuser width, for centrifugal compressor were studied experimentally. Along with the diffuser width, the tip clearance was altered. The compressor overall performance and ...
    • Effects of Different Blade Angle Distributions on Centrifugal compressor performance 

      Röyttä, Pekka; Grönman, Aki; Jaatinen, Ahti; Turunen-Saaresti, Teemu; Backman, Jari (Hindawi, 2009)
      A centrifugal compressor with three different shrouded 2D impellers is studied numerically. All impellers have the same dimensions, and they only differ in channel length and geometry. Noticeable differences in efficiency ...
    • Performance and flow fields of a supersonic axial turbine at off-design conditions 

      Grönman, Aki; Turunen-Saaresti, Teemu; Röyttä, Pekka; Jaatinen, Ahti; Backman, Jari (Institution of Mechanical Engineers, 2013)
      The increasing demand of energy efficiency and the utilisation of small-scale energy sources require efficient, small and versatile turbines. Supersonic turbines have a high power density and therefore small size and fewer ...
