2025 Project: Improving the Performance of Hydrodynamic Tilting-pad Thrust Bearings in Hydropower Plants
10 weeks: June 2-Aug 8
Our project focuses on enhancing the performance of tilting pad hydrodynamic thrust bearings (TPHTBs) used in hydropower generators by introducing optimized surface textures. Through computational modeling, mechanical design, manufacturing, and experimental testing, we aim to validate the improved efficiency and reliability of these bearings. The adoption of surface-textured TPHTBs in hydropower plants has the potential to deliver significant cost savings and environmental benefits by improving energy efficiency and extending equipment lifespan.
Dr. Anbara Lutfullaeva's research examines hydrodynamic thrust bearings under changing loads.
Hydrodynamic thrust bearings are specialized components used to support axial loads in rotating machinery by creating a thin film of lubricant (usually oil) between the rotating and stationary surfaces. This allows the rotor to float, reducing friction and wear. These bearings are crucial in applications requiring high loads and smooth operation, such as turbines, generators, compressors and pumps.
The new lab will design and fabricate an experimental test rig. Then Dr. Lutfullaeva's research team will be able to conduct an experimental analysis to investigate bearing performance characteristics such as pressure generation, oil film thickness, and temperature.
