Modeling of Partially Wetting Liquid Film Using an Enhanced Thin Film Model for Aero-Engine Bearing Chamber Applications. Journal of Engineering for Gas Turbines and Power, 143(4), Article 041001. https://doi.org/10.1115/1.4049663

In the case of aero-engine, thin lubricating film servers dual purpose of lubrication and cooling. Prediction of dry patches or lubricant starved region in bearing or bearing chambers are required for safe operation of these components. In this work,...

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

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...

Prediction of Film Thickness of an Aero-Engine Bearing Chamber using Coupled VOF and Thin Film Model (2019)
Conference Proceeding
Singh, K., Sharabi, M., Ambrose, S., Eastwick, C., & Jefferson-Loveday, R. J. (2019). Prediction of Film Thickness of an Aero-Engine Bearing Chamber using Coupled VOF and Thin Film Model. In Proceedings of ASME Turbo Expo 2019 Turbomachinery Technical Conference & Exposition

In the present work, a coupled volume-of-fluid (VOF) model with Eulerian thin-film model (ETFM) approach is used to predict the film thickness in an aero-engine bearing chamber. Numerical studies are conducted for a wide range of shaft speeds with lu... Read More about Prediction of Film Thickness of an Aero-Engine Bearing Chamber using Coupled VOF and Thin Film Model.

Uncertainties in pressurized thermal shock analyses (2019)
Conference Proceeding
Niffenegger, M., Garrido, O. C., Mora, D., Qian, G., Mukin, R., Sharabi, M., …Niceno, B. (in press). Uncertainties in pressurized thermal shock analyses. In Proceedings of the ASME 2019 Pressure Vessels & Piping Conference PVP2019

Integrity assessment of reactor pressure vessels (RPVs) can be performed either by deterministic fracture mechanics (DFM) or/and by probabilistic fracture mechanics (PFM) analyses. In European countries and Switzerland, only DFM analyses are required... Read More about Uncertainties in pressurized thermal shock analyses.
