Proceedings Papers

Proc. ASME. GT2021, Volume 9B: Structures and Dynamics — Fatigue, Fracture, and Life Prediction; Probabilistic Methods; Rotordynamics; Structural Mechanics and Vibration, V09BT29A007, June 7–11, 2021
Paper No: GT2021-58747
...Abstract Abstract One of the major noise sources of high bypass ratios modern turbofan engines arises from the interaction between the turbulent rotor wake, the tip-leakage and the leading edge of the downstream outlet guide vanes. Recent research has confirmed that leading edge serrations...

Proc. ASME. GT2021, Volume 5A: Heat Transfer — Combustors; Film Cooling, V05AT12A023, June 7–11, 2021
Paper No: GT2021-59780
...Abstract Abstract In gas turbine engines, the highest heat loads occur at the leading-edge areas of turbine blades and vanes. To protect the blades and vanes, a “showerhead” configuration of film cooling holes is often used for this location, in which several rows of holes are configured...

Proc. ASME. GT2020, Volume 7B: Heat Transfer, V07BT12A064, September 21–25, 2020
Paper No: GT2020-15975
...Abstract Abstract Under the effect of inlet distortion profiles (including hot-streaks, total pressure profiles, and swirling flow angle patterns), the film cooling performance on the leading edge (LE) region of GE-E 3 nozzle guide vanes (NGVs) has been numerically investigated in this paper...
