Effect of radial transport on compressor tip clearance flow structures and enhancement of stable flow range

  title={Effect of radial transport on compressor tip clearance flow structures and enhancement of stable flow range},
  author={Sean Patrick Rock Nolan},
The relation between tip clearance flow structure and axial compressor stall is interrogated via numerical simulations, to determine how casing treatment can result in improved flow range. Both geometry changes and flow field body forces are used as diagnostics to assess the hypothesis that the radial transport of momentum out of the tip region, and the consequent decrease in streamwise momentum in this region, is a key aspect of the flow. The radial velocity responsible for this transport is a… 
The Role of Tip Leakage Flow in Spike-Type Rotating Stall Inception
The role of tip leakage flow in creating the leading edge separation necessary for the onset of spike-type compressor rotating stall is described and guidelines are developed for flow range enhancement through control ofTip leakage flow axial momentum magnitude and distribution.
