Visualization investigation on flow field of journal bearing with partial texture surface

The effect of partial texture surface on flow field of journal bearing is investigated experimentally using a visualization apparatus, which was less reported before. The visualization results show that there is a speeding-up phenomenon in the movement of lubricant when lubricant flows from smooth surface region to dimple surface region, and the rising ratio of lubricant speed increases with the rotational speed of journal shaft.
