A two-dimensional computational fluid dynamics model was developed and an experiment was performed to investigate the role of pocket texture on fully lubricated motion with the cavitation effect. This paper discusses the cavitated simulation models and experiments to describe texture cavitation to solve the lubricating properties of the textured friction pair. The effects of velocity and texture scale on the support force and friction coefficient are discussed. It was found that the results of the two-dimensional computational fluid dynamics model with cavitation are nearly consistent with the experimental results; the hydrodynamic pressure decreased and the sliding speed dropped, and the effect of pressure became highly pronounced with ideal texture size. In addition, the simulation solution can show the internal flow field, and extend the solutions to large-scale textures and multiple textures. Meanwhile, appropriate texture parameters can optimize the friction coefficient and support force. The texture depth ratio plays a more important role on the value of the support force, and the width ratio has a greater influence on the friction coefficient.
