Experimental investigation of effect of the surface texture configuration on hydrodynamic performance under oil lubricated rotating condition

Abstract

A series of experiments is conducted to investigate the hydrodynamic performance of samples with different surface texture configurations. Two kinds of dimple texture configurations are designed: circumferential radiation distributed partial texturedsample and equal distance distributed fully textured sample. The none textured sample is taken as a contrast one. In the test, gap between tested specimen and the geometric probe is set at 20 μm. By changing the rotating speed of the geometric robe, the load-carrying capacity measured is constantly changing. It is found that the load-carrying capacity is strongly influenced by the surface texture configuration and the operation condition.
