This study examines the performance of finite-length textured journal bearings under fully turbulent conditions using Constantinescu’s turbulence model in the Reynolds equation. Circular textures, resembling cylindrical grooves, were strategically distributed across various angular zones. A validated numerical model analyzed 20 texture configurations to assess their impact on turbulence, pressure, and load capacity. Results indicate that full texturing increases turbulence, reducing performance, while partial texturing (225°–360°) enhances load capacity, matching, or exceeding non-textured bearings. Parametric analysis reveals texture depth and density significantly affect performance, whereas texture radius has a minor impact. These findings offer insights for optimizing textured journal bearings in turbulent regimes.
