Short summary
This study explores how grease moves inside large rotating components used in wind turbines. Using advanced computer simulations, we modeled the real-life behavior of grease under the influence of gravity and motion. Our findings show that the tilt and size of the component greatly affect how grease spreads and performs. This helps improve the design and reliability of wind turbines for long-term, efficient energy production.
