  2. Overview • Introduction • Facilities • Instrumentation • Current Activities • Conclusions 1ST ANNUAL FlowPAC INDUSTRY PARTNER MEETING

  3. Introduction • Fluid structure interaction is seen in many types of applications. • Automotive • Marine • Aerospace • Problems • High cycle fatigue • Noise generation 1ST ANNUAL FlowPAC INDUSTRY PARTNER MEETING

  4. Facilities • Anechoic Chamber with wind tunnel (AWT) • Subsonic and supersonic wind tunnels • Atmospheric wind tunnel • Planar Jet facility 1ST ANNUAL FlowPAC INDUSTRY PARTNER MEETING

  5. Instrumentation • 2 arrays of 40 microphones each • 3-D Digital Particle Image Velocimetry (PIV) • Single point Laser Doppler Vibrometer (LDV) • Scanning LDV (SLDV) Array #1 Flow Array #2 1ST ANNUAL FlowPAC INDUSTRY PARTNER MEETING

  8. Instrumentation • 2 arrays of 40 microphones each • 3-D Digital Particle Image Velocimetry (PIV) • Single point Laser Doppler Vibrometer (LDV) • Scanning LDV (SLDV) 1ST ANNUAL FlowPAC INDUSTRY PARTNER MEETING

  9. Current Activities • Turbulent Boundary Layer Interactions with elastic end wall • Hydrodynamic pressures force vibrations in end wall. • Scanning LDV used to record vibrational pattern of endwall 1ST ANNUAL FlowPAC INDUSTRY PARTNER MEETING

  10. Current Activities • Add Airfoil Tip to turbulent boundary layer. • Complicated system of coupled hydrodynamic and acoustic pressures. • Use unsteady force transducers with scanning and single point LDV to correlate unsteady force with vibrational pattern of endwall. 1ST ANNUAL FlowPAC INDUSTRY PARTNER MEETING

  11. Current Activities • Sound Radiation From A Submersed Elastic Duct in Nonuniform Flow 1ST ANNUAL FlowPAC INDUSTRY PARTNER MEETING

  12. Summary • Fluid structure interactions significantly impact design considerations. • Instrumentation • 2 arrays of 40 microphones each • 3-D Digital PIV • Single Point and Scanning LDV • Facilities • AWT, sub- and supersonic tunnels, planar jet 1ST ANNUAL FlowPAC INDUSTRY PARTNER MEETING
