JEFF(A) Mixed-Flow Model Fan Performance Optimization.

Abstract

This Model Test Program was conducted in order to improve the performance of the JEFF(A) Mixed-Flow Fan. Both rotor and housing changes were made to the existing model fan and tests were conducted in the ALRC Physics Laboratory. Rotor modifications consisted of varying blade length and narrowing the rotor width at the exit. Housing size was varied by changing axial and radial dimensions. The sensitivity of fan performance to IGV positioning was also determined for both flat and twisted vanes. Finally, full size fan performance was predicted for the best combination of housing and rotor. Recommendations are also made for further improvement of the Mixed-Flow Fan concept.
