| | In previous work of Schulz et al. 4, different actuating devices like piezo-electrically driven lips, cylindrical rods (Neuhaus et al. 5) as well as steady or unsteady air injection were tested.... Steady injection of compressed air via wall flush mounted cylindrical nozzles between rotor and stator turned out to be the most effective method with BPF level reductions up to 20 dB. Note that this type of air injection through the casing wall is not aimed at filling the rotor wakes as was done by Fitel et al. 6, but to generate additional unsteady blade forces.... |
