    • GPUs - Cheap Supercomputing 

      Pullan, Graham (2008-11-11)
    • Modeling Nonuniform Bleed in Axial Compressors 

      Grimshaw, Samuel; Pullan, Graham; Hynes, Thomas Paul (American Society of Mechanical Engineers, 2016-04-12)
      The coupling between the bleed system and the flowfield of a downstream compressor stage is studied using two approaches. In the first approach, three-dimensional, full annulus, unsteady computations simulate the flow in ...
    • The Role of Tip Leakage Flow in Spike-Type Rotating Stall Inception 

      Hewkin Smith, Maximilian; Pullan, Graham; Grimshaw, SD; Greitzer, EM; Spakovszky, ZS
      This paper describes the role of tip leakage flow in creating the leading edge separation necessary for the onset of spike-type compressor rotating stall. A series of unsteady multi-passage simulations, supported by ...
    • Secondary Flow Control in Low Aspect Ratio Vanes Using Splitters 

      Clark, Christopher James; Pullan, Graham; Curtis, E; Groenaga, F (American Society of Mechanical Engineers, 2017-09)
      Low aspect ratio vanes, often the result of overall engine architecture constraints, create strong secondary flows and high end-wall loss. In this paper, a splitter concept is demonstrated that reduces secondary flow ...
