| Title: | The influence of compressor outlet conditions on the performance of annular diffusers |
| Authors: | Harasgama, Sriwickrama P. |

| Abstract: | Experiments have been carried out on an
Optimum (C •) Diffuser (Area Ratio- 2:1) to investigate
the way in which compressor exit conditions influence
the performance and boundary layer growth within the
diffuser. Three sets of conditions simulated by 0°,
15° and 30° Radially Tilted O.G.V. (outlet guide vanes)
have been studied. Compressor delivery conditions were
simulated by a single Rotor row just upstream of the
O.G.V. The Rotor/O.G.V. constituted a single compressor
stage and was sited 0.125 blade chord lengths upstream
of diffuser inlet.
The diffuser static pressure recovery, total pressure loss and flow stability were, in all
cases, better than that achieved with fully developed
flow at inlet to the diffuser. The 30o O.G.V. configuration
being the most superior [continued]… |
