TLDR
In this article, a hydrodynamic numerical model with global thermal effects is employed to evaluate the performance degradation of scratched journal bearings by means of numerical simulations, where a very fine mesh is used, which allows a deterministic representation of a large number of circumferential scratches.About:

Influence of Scratches on the Performance of a Partial Journal Bearing
Mihai B. Dobrica,Michel Fillon +1 more
TL;DR: In this article, the influence of circumferential scratches on the thermohydrodynamic performance of a partial (lobe) journal bearing is studied. And the types of wear profiles that can lead to the bearing destruction (characterized by a critical minimum film thickness) are also investigated.
