| Abstract: | Numerical simulations were carried out to study the pure-oil lubricated journal bearing by using the cavi-tation model of FLUENT. The temperature increment of the bearing was given and compared with the experimental value, the results agreed well. The relation between bearing capacity and eccentricity under different rotation speed and length-diameter ratios （ L/D） were calculated, the oil film pressure distribution with different eccentricity was derived, and the gas phase mass distribution rules were discussed in this paper. |
