Abstract
Surface texturing with slip can have a significant effect on the lubrication performance in hydrodynamic bearing. In the present paper, the texture shape consisting of parabola, rectangular, and triangular for partially texture bearing is of particular interest. Number of the texture cells are also varied to obtain the optimal tribological performance in terms of load support and friction force. The slip is located at the leading edge of the contact to achieve the highest performance. The modified Reynolds equation with slip is adopted and discretized using finite volume method. The tridiagonal matrix algorithm is used to solve this equation. The numerical results show that the number of texture cells has a significant effect on the load support as well as the friction force. However, it is also found that there is no texture shape which is superior for all performances. Thus, a particular care must be chosen with respect to the number of textures as well as the texture shapes to obtain the optimal tribological performance. This finding can be used as a guideline to design the bearing with optimal performance.
