Singh, K., Sharabi, M., Ambrose, S., Eastwick, C., Jefferson-Loveday, R., Cao, J., & Jacobs, A. (2019, June). Assessment of an Enhanced Thin Film Model to Capture Wetting and Drying Behavior in an Aero-Engine Bearing Chamber. Presented at ASME Turbo Expo 2019 Turbomachinery Technical Conference & Exposition, Phoenix, Arizona, United States

In the present work, a wetting and drying model is coupled with Eulerian Thin-Film model (ETFM) to analyze the wetting and drying behavior inside the bearing chamber. In the enhanced model, an additional source term is included to account for the con...

COUPLED EULERIAN THIN FILM MODEL AND LAGRANGIAN DISCRETE PHASE MODEL TO PREDICT FILM THICKNESS INSIDE AN AERO-ENGINE BEARING CHAMBER
Presentation / Conference Contribution
Mouvanal, S., Singh, K., Jefferson-Loveday, R., Ambrose, S., Eastwick, C., Johnson, K., & Jacobs, A. (2022, September). COUPLED EULERIAN THIN FILM MODEL AND LAGRANGIAN DISCRETE PHASE MODEL TO PREDICT FILM THICKNESS INSIDE AN AERO-ENGINE BEARING CHAMBER. Presented at GPPS Chania22, Chania, Greece

In aero-engine bearing chambers, two-phase shearing flows are difficult to predict as Computational Fluid Dynamics (CFD) RANS models tend to overestimate interfacial turbulence levels, leading to inaccuracies in the modelling of the flow. Turbulence... Read More about COUPLED EULERIAN THIN FILM MODEL AND LAGRANGIAN DISCRETE PHASE MODEL TO PREDICT FILM THICKNESS INSIDE AN AERO-ENGINE BEARING CHAMBER.

CFD modelling of an entire synchronous generator for improved thermal management
Presentation / Conference Contribution
Connor, P. H., Pickering, S. J., Gerada, C., Eastwick, C. N., & Micallef, C. (2012, March). CFD modelling of an entire synchronous generator for improved thermal management. Presented at 6th IET International Conference on Power Electronics, Machines and Drives (PEMD 2012), Bristol, UK

This paper is the first in a series dedicated to investigating the airflow and thermal management of electrical machines. Due to the temperature dependent resistive losses in the machine's windings any improvement in cooling provides a direct reducti...
