Flow control in axial fan inlet guide vanes by synthetic jets
Result description
Tested high pressure axial flow fan with hub/tip ratio of 0.70 and external diameter of 600 mm consisted of inlet guide vanes (IGV), rotor and stator blade rows. Fan peripheral velocity was 47 m/s. Air volume flow rate was changed by turning of rear partof IGVs. At turning of 20°, flow separation occurred on the IGVs. Radial synthetic jets (500?700 Hz) were introduced before flow separation origin. It favorably influenced separated flow: at the distance of 5?12 mm from the casing surface, a reduction of flow separation decreased the profile loss coefficient approximately by 20 %.
