Behavior Of Scratched Hydrodynamic Journal Bearings Tran-Anh Vo

This work contributes to the overall knowledge of the behaviors of damaged journal bearings. In particular, the influence of presence of the scratches on the performance of scratched journal bearings. A numerical thermohydrodynamic model has been developed, it is able to simulate the influence of scratches on the characteristics of the bearing, including the pressure, flow rates, temperature, operating conditions, and other relevant parameters. It is also able to determine limits of operation of scratched journal bearings. The numerical analysis of the performance of scratched journal bearings are also provided with a variety of configurations of the scratch geometry and operating conditions.
