Assessment of the Oil Scoop Capture Efficiency in High Speed Rotors (2018)
Journal Article
Paleo Cageao, P., Simmons, K., Prabhakar, A., & Chandra, B. (2019). Assessment of the Oil Scoop Capture Efficiency in High Speed Rotors. Journal of Engineering for Gas Turbines and Power, 141(1), Article 012401. https://doi.org/10.1115/1.4040812

Experimental research was conducted into a scooped rotor system that captures oil from a stationary jet and directs it through passages within the shaft to another axial location. Such a system has benefits for delivering oil via under-race feed to a... Read More about Assessment of the Oil Scoop Capture Efficiency in High Speed Rotors.

Numerical investigations to assess the impact of shaft speed on the performance of scoop devices (2018)
Presentation / Conference Contribution
Prabhakar, A., Abdalla Abakr, Y., & Simmons, K. (2018, June). Numerical investigations to assess the impact of shaft speed on the performance of scoop devices. Presented at ASME Turbo Expo 2018: Turbomachinery Technical Conference and Exposition, Oslo, Norway

The demand for continuous and efficient lubrication in aeroengine bearing assemblies has encouraged the development of scoop based lubrication systems. Using a scooped rotor in conjunction with axial passages within the shaft, a scoop system can prov...
