Goal: Determine how FSTI effects endwall flow structure behavior and losses in the region
Application: LPT, Endwall Flows, Junction Flows
Approach: Vary the incoming FSTI level in a low-speed linear cascade of seven L2F blades by installing a grid 2.3m upstream of cascade with 2.54 cm bars and 7.6 cm center to center spacing. Grid has an active option by having pairs of jets in the tubes angled and oriented downstream. Investigate the flow using high speed SPIV collected in the passage at 2.5kHz.
