Scavenge flow in a bearing chamber with tangential sump off-take (2013)
Journal Article
Munson, J. H., Collicott, S. H., Chandra, B., Collicott, S., & Munson, J. (2013). Scavenge flow in a bearing chamber with tangential sump off-take. Journal of Engineering for Gas Turbines and Power, 135(3), https://doi.org/10.1115/1.4007869

A tangential sump design is employed in several aero-engines mainly due to its simplicity and compactness. However various problems have prompted investigations of the sump design. An experimental program at Purdue University (Chandra, 2006, "Flows i... Read More about Scavenge flow in a bearing chamber with tangential sump off-take.

Study of gas/liquid behavior within an aeroengine bearing chamber (2013)
Journal Article
Wiedemann, N., Collicott, S. H., Chandra, B., Simmons, K., Pickering, S., Collicott, S., & Wiedemann, N. (2013). Study of gas/liquid behavior within an aeroengine bearing chamber. Journal of Engineering for Gas Turbines and Power, 135(5), https://doi.org/10.1115/1.4007753

Aeroengine bearing chambers typically contain bearings, seals, shafts and static parts. Oil is introduced for lubrication and cooling and this creates a two phase flow environment that may contain droplets, mist, film, ligaments, froth or foam and li...

Performance comparison for aeroengine-type sump geometries (2013)
Conference Proceeding
Keeler, B., Chandra, B., Simmons, K., & Keeler, B. (2013). Performance comparison for aeroengine-type sump geometries. In Volume 1: Advances in Aerodynamics. https://doi.org/10.1115/IMECE2013-62836

Oil removal from aeroengine bearing chambers presents a challenge for aeroengine designers. Effective scavenging of oil is necessary to avoid excessive heat in the bearing chamber as this may lead to degradation of oil properties and deterioration in...
