In recent years, detailed analyses of lubricating oil flow using computational fluid dynamics were carried out for fluid lubrication on textured surfaces. Most of them are performed for steady state and with use of a fixed geometry. However, the unevenness on the surfaces moves each other in the sliding region and the film thickness and the geometry change. Therefore, it is necessary to perform unsteady analysis with use of the geometry changes. The purpose of this study was to obtain knowledge about the of sliding characteristics on the textured surface considering the unsteady state. Immersed boundary method is used for reproducing for the geometry changes on the texture. From the analysis results, it was clarified that the shape of the sliding surface has a large effect on the sliding characteristics.
