Abstract

A turbulence generating grid has been used to increase the level of free-stream turbulence inside a 1.5 stage axial compressor to values typical of an embedded stage in a multi-stage machine.Hot-wire measurements taken in the rotor-stator axial gap have been ensemble-averaged to determine periodic fluctuations in turbulence level and velocity. These results are compared to measurements made at low turbulence levels without the turbulence grid. Increasing levels of free-stream turbulence are shown to reduce the magnitude of periodic disturbances produced by viscous interaction between the inlet guide vane (IGV) and rotor blade wakes.
