Journal Bearings with Hydrophobic Surface

Abstract In the article there is presented a modified Reynolds equation. The equation includes the effect of fluid slipping at partially hydrophobic surface. Bearing with the hydrophobic surface of the lining is characterized by a reduction of stiffness and damping for a maximum of one quarter of the original value in comparison with the hydrophilic lining. Significantly, however, decreases the value of dissipation function and thus the hydraulic losses in the bearing. In addition, increases the critical value of Taylor number.
