The investigation is part of a program addressing the behavior of disturbances in strongly swirling flows. There is evidence that the wakes are radially outward and carry static pressure disturbances with them. The harmonic analysis of the static pressure measured at the tip radius indicates a shift toward higher frequency of the peak in the power spectrum as the flow proceeds downstream. It is suggested that this increasing frequency associated with the power peak results from the wakes being convected downstream in a fluid which has increasing swirl velocity as it travels away from the rotor. The research was performed on the Blowdown Compressor, constructed under NASA Grant NGL-22-009-3 Support in the form of a Research Assistantship was provided the author by Pratt & Whitney Aircraft, Division of United Aircraft Corporation 2016-09-27T19:59:00Z 2016-09-27T19:59:00Z 1974 Technical Report http://hdl.handle.net/1721.1/104406 02133215 GTL report #118 64 pages application/pdf Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, 1974 |
