abstract

Tests have been conducted on an annular, Hybrid Diffuser, of short length while operating in isolation. The purpose was to ascertain whether such a diffuser could operate efficiently without the downstream influence of the combustor dome which had been a feature of previous tests. The diffuser was fitted with a pre-diffuser in order to raise the static pressure level of the bleed air. A series of exit cones was used as the final stage of diffusion, covering a range of included angle from 15 to 45 degrees.

Results obtained demonstrate that this configuration of Hybrid diffuser operates efficiently, that performance is improved if pressures inside the inner and outer vortex chambers are balanced, and that larger quantities of bleed must be extracted in order to maintain a high pressure recovery as the exit included angle is increased.
