Experimental investigation into droplet impingement upon moving films using high speed video and thermal imaging (2015)
Presentation / Conference Contribution
Mitchell, A. J., Simmons, K., & Hann, D. B. Experimental investigation into droplet impingement upon moving films using high speed video and thermal imaging. Presented at ASME 2015 International Mechanical Engineering Congress & Exposition (IMECE 2015)

Aeroengine bearing chambers are geometrically complex, typically containing shafts, bearings, seals and stationary components. Oil is supplied for lubrication and cooling and so the chamber contains a highly rotating two-phase (oil/air) flow where th...

Velocity measurements in the vicinity of the exit and inlet of a spiral bevel gear shroud (2015)
Presentation / Conference Contribution
Simmons, K., & Johnson, G. Velocity measurements in the vicinity of the exit and inlet of a spiral bevel gear shroud. Presented at ASME Turbo Expo 2015: Turbine Technical Conference and Exposition

In many aeroengines the accessory power offtake is achieved using a spiral bevel gear set running off one of the main shafts. The crown and bevel gears are housed in an internal gearbox. Over the past few years the Nottingham University Technology Ce... Read More about Velocity measurements in the vicinity of the exit and inlet of a spiral bevel gear shroud.
