A machine learning-driven approach to predicting thermo-elasto-hydrodynamic lubrication in journal bearings (2024)
Journal Article
Cartwright, S., Rothwell, B. C., Figueredo, G., Medina, H., Eastwick, C., Layton, J., & Ambrose, S. (2024). A machine learning-driven approach to predicting thermo-elasto-hydrodynamic lubrication in journal bearings. Tribology International, 196, Article 109670. https://doi.org/10.1016/j.triboint.2024.109670

Traditional methods of evaluating the performance of journal bearings, for example thermal-elastic-hydrodynamic- lubrication theory, are limited to simplified conditions that often fail to accurately model real-world components. Numerical models that... Read More about A machine learning-driven approach to predicting thermo-elasto-hydrodynamic lubrication in journal bearings.

Windage Torque Reduction in Low-Pressure Turbine Cavities Part I: Concept Design and Numerical Investigations (2024)
Journal Article
Li, Z., Christodoulou, L., Jefferson-Loveday, R. J., Ambrose, S., Jackson, R., Lock, G. D., …Scobie, J. (2024). Windage Torque Reduction in Low-Pressure Turbine Cavities Part I: Concept Design and Numerical Investigations. Journal of Turbomachinery, 146(6), 1-16. https://doi.org/10.1115/1.4064224

The windage torque on rotational walls has negative effect on the performance of the low pressure turbine. In this paper, three novel flow control concepts (FCCs) were proposed to reduce the windage torque within a turbine stator well, with upstream...

Windage Torque Reduction in Low-Pressure Turbine Cavities Part II: Experimental and Numerical Results (2024)
Journal Article
Jackson, R. W., Li, Z., Christodoulou, L., Ambrose, S., Sangan, C. M., Jefferson-Loveday, R., …Scobie, J. A. (2024). Windage Torque Reduction in Low-Pressure Turbine Cavities Part II: Experimental and Numerical Results. Journal of Turbomachinery, 146(6), Article 061005. https://doi.org/10.1115/1.4063876

Minimizing the losses within a low-pressure turbine (LPT) system is critical for the design of next-generation ultra-high bypass ratio aero-engines. The stator-well cavity windage torque can be a significant source of loss within the system, influenc...
