Mixed-lubrication analysis of marine stern tube bearing considering bending deformation of stern shaft and cavitation

Effect of Surface Topography and Structural Parameters on the Lubrication Performance of a Water-Lubricated Bearing: Theoretical and Experimental Study

“…Pressure under the From Figure 8, we can see that this study's simulation corresponds well with the literature under two boundary conditions, the Reynolds boundary condition and the Jakobsson-Floberg-Olsson (JFO) boundary condition, which proves the accuracy of the model and algorithm. Pressure under the Reynolds boundary conditions shows better correspondence with the reference [20]. The following calculation is based on this model under the Reynolds boundary conditions.…”

“…The following calculation is based on this model under the Reynolds boundary conditions. Reynolds boundary conditions shows better correspondence with the reference [20]. The following calculation is based on this model under the Reynolds boundary conditions.…”

“…The accuracy and reliability of the model and algorithm were prerequisites for the study. The accuracy of the model was verified by comparing the results with reference [20]. Figure 7 presents the schematic diagram of the relative position of Sections 1 and 2 on the test bearing.…”

“…For JFO boundary conditions [20], the calculated pressure distribution is limited to the positive pressure region, and both the cavitation upper and lower boundaries are based on the mass conservation equation. In the cavitation region, the pressure is equal to the cavitation pressure P cav , whereas in the rupture region (x 0 ,z 0 ),…”

“…Researchers make great efforts to improve the lubrication performance [1][2][3] of the bearing, such as the exploitation of surface textures [4][5][6], the optimum design of bearing structures [7][8][9], and the introduction of longitudinal grooves. Many studies [10][11][12] focused on the effect of surface topography [13] on the bearing performance [10,[14][15][16][17][18][19][20]. For example, Tala-Ighil et al [21] investigated the modeling of journal bearing characteristics.…”
