• Free-form versus ruled inducer design in a transonic centrifugal impeller

  H Hazby, C Robinson, M Casey, D Rusch and R Hunziker

  • Free form versus ruled inducer design in a transonic centrifugal impeller
    A comparison between free-form, fully 3D centrifugal compressor impellers featuring sweep and advanced Mach number control vs. conventional, ruled-surface impellers, including comparisons with test data.

• The design of a family of process compressor stages

  HR Hazby, MV Casey, CJ Robinson, R Spataro

  • The design of a family of process compressor stages
    The design of a family of shrouded, centrifugal compressor stages for application in multistage barrel compressors is described from first principles through to detailed design, advanced CFD and comparisons with test data.

• Effects of blade deformation on the performance of a high flow coefficient mixed-flow impeller

  HR Hazby, I Woods, MV Casey, R Numakura and H Tamaki

  • Effects of blade deformation on the performance of a high flow coefficient mixed-flow impeller
    A study on the effects of blade deformation due to centrifugal forces on the aerodynamic performance of a mixed-flow impeller.Twistng of the blade affected capacity and changes in peak performance were found to correlate with a change in blade clearance.

• Transient flow characteristics of con/co-rotating swirler arrangements of an industrial combustor

  X Wu, ER Norster and G Xie

  • Transient flow characteristics of con/co-rotating swirler arrangements of an industrial combustor
    A comparison between contra and co-rotating swirlers in a combuster in and industrial gas turbine based on transient CFD with ANSYS CFX.

• The evolution of turbomachinery design (methods)

  Professor John Denton

  • The evolution of turbomachinery design (methods)
    A lecture on turbomachinery analysis given by Professor John Denton on the occasion of PCA's 20th anniversary celebration in 2009.

• Design and testing of a high flow coefficient mixed flow impeller

  HR Hazby, MV Casey, R Numakura and H Tamaki

  • Design and testing of a high flow coefficient mixed flow impeller
    An exercise in pushing the boundaries of the design space for centrifugal compressor stages to much higher specific flow than is usual in today's designs. The highly 3D blades use sweep and lean to control shroud Mach numbers.
