Study on hydrodynamic lubrication with second-order fluid (II) - NumericalAnalysis

The basic lubrication equations are used to calculate two kinds of lubricat ions examples, a plane inclined slider and a journal bearing respectively. In the calculation of the journal bearing, the Reynolds' boundary condition s are used. In the calculation, it is found that the load carrying capaciti es of the slider and the journal are of different tendencies with increase in Deborah number. Furthermore, the results show that with decrease in the film thickness the increase in the normal stress of second-order fluid is g reater than that of Newtonian fluid. Finally, it is found that the distribu tion of the normal stress changes significantly at a certain thickness.
