Endwall Vortices in a High-Lift High-Work Low Pressure Turbine Passage (December 2020): This flow visualization image highlights the complexity of the unsteady fluid dynamics in the endwall region of high-lift high-work turbine passage. Multiple vortical structures are shown. The image was extracted from high-speed video acquired in the AFRL Aerospace Systems Directorate, Turbine Engine Division, low speed linear cascade wind tunnel.
