Numerical Analysis of the Mixed-Lubrication Performance of Staved Stern Tube Bearings Lubricated with Water

The present study aims to establish a mixed lubrication model for staved stern tube bearings lubricated with water, in which the average Reynolds equation and KE elastic–plastic contact are introduced calculate hydrodynamic pressure pressure, respectively. difference behaviors between circular- flat-staved is compared; moreover, effects of number staves on mixed-lubrication performance these two kinds bearing investigated. mechanism action revealed. numerical results show that has significant effect bearings. Furthermore, there an optimal value staves, shown be 30 current simulation, improving water.
