Presentation / Conference Contribution
Sinha, A., Hann, D., Johnson, K., & Walsh, M. (2022, June). Experimental investigation into oil film thickness and behaviour near an aero-engine bearing. Presented at ASME Turbo Expo 2022: Turbomachinery Technical Conference and Exposition, Rotterdam, Netherlands

In an aero-engine transmission system, bearings are used for shaft location and load support. These bearings are housed in bearing chambers and oil is supplied to the chamber for lubrication and cooling. To achieve the targets of ACARE Flightpath 205...

How Do Interfacial Shear and Gravity Affect the Oil Film Characteristics Near an Aero-Engine Bearing? (2022)
Journal Article
Sinha, A., Brewster, B., Johnson, K., Walsh, M., & Hann, D. (2022). How Do Interfacial Shear and Gravity Affect the Oil Film Characteristics Near an Aero-Engine Bearing?. Journal of Engineering for Gas Turbines and Power, 144(10), Article 101001. https://doi.org/10.1115/1.4055211

Recent demand for reducing carbon emission and for increasing engine efficiency has led aero-engine manufacturers to strive for a better oil flow system. Aero-engine bearing chambers that house the shaft-support bearings are among the most challengin...

Can simultaneous PIV in the gas and liquid phases provide insight into the transfer of momentum between the two phases? (2022)
Presentation / Conference Contribution
Kim, J. H., Hann, D. B., Eastwick, C. M., & Cherdantsev, A. V. (2022, July). Can simultaneous PIV in the gas and liquid phases provide insight into the transfer of momentum between the two phases?. Presented at 20th International Symposium on the Application of Laser and Imaging Techniques to Fluid Mechanics, Lisbon, Portugal

Understanding the interaction between a gas shearing over a liquid film and the liquid film is essential if we wish to use modeling to optimize systems to decrease environmental impact, increase efficiency and hence productivity. To this end, PIV is... Read More about Can simultaneous PIV in the gas and liquid phases provide insight into the transfer of momentum between the two phases?.

Studying the impacts of droplets depositing from the gas core onto a gas-sheared liquid film with stereoscopic BBLIF technique. (2022)
Journal Article
Cherdantsev, A. V., Sinha, A., & Hann, D. B. (2022). Studying the impacts of droplets depositing from the gas core onto a gas-sheared liquid film with stereoscopic BBLIF technique. International Journal of Multiphase Flow, 150, Article 104033. https://doi.org/10.1016/j.ijmultiphaseflow.2022.104033

In annular gas-liquid flow, the droplets are torn from the liquid film surface by the turbulent gas stream, accelerate due to the gas drag force and eventually deposit back onto the wavy film surface, hitting it with a high speed at a shallow angle....
