Objectives
- Enable unobstructed 2 and 3 dimensional particle imaging velocimetry (PIV) and holographic (HPIV) measurements within entire stage of an axial flow turbomachine.
- Study
Unsteady flow phenomena
Rotor stator interaction
Secondary flows
Tip leakage
Hub vortices
- Identify sources of noise and pressure fluctuations
- Generate data for development in turbulence models:
Passage averaged, steady RANS
Unsteady RANS
Large eddy simulation
- Study the effect of inlet conditions (such as, inflow turbulence level and non-uniformities)
- Future extentions: Instantaneous velocity fileds condistional upon certain variables such as, wall pressure on blade surface
