| Summary: | Abstract Hydrostatic bearings are expected to attract significant attention in the coming years due to their wide use in engineering applications, such as high-speed machine tool spindles, fast-moving machinery, and precision grinding tools. However, there is still a need to better understand the flow behavior related to different pressure pocket patterns. The aim of this research is to investigate how the supplied pressure and the shape of the pocket affect the pressure distribution in hydrostatic bearings with rectangular pads. Using the 3D Navier–Stokes equations and the finite volume method in ANSYS-CFD-19 R3, different recess designs — specifically rectangular and circular recesses — were analyzed to determine their impact on static pressure. The results showed that conical-shaped recesses produced higher pressure values compared to non-conical shapes. This study focused on two main types of recess shapes: rectangular and circular. |
