With the increase of the dimensionless wall viscosity η*W, the velocity of the close-adsorption layer changes less and less, and the shift zone is mainly in the low-viscosity zone of the intermediate layer. In this zone, the velocity gradient is large, and the friction characteristics of the bearing are mainly It is decided by this zone. The increase in wall viscosity, the greater the impact on speed, the speed change is concentrated in the middle layer, at this time, the middle layer shows a large velocity gradient. From the ratios at different viscosities, it can be seen that the increase in δ* clearly shows the non-linearity of the liquid. The velocity of the adsorption layer in the exit zone is significantly different from that in the entrance zone, and the rate of change in the speed in the exit zone is much greater than in the entrance zone. At the same time, the fluid in the adsorption layer is reduced due to the strong adsorption effect and the velocity difference of the solid wall surface. Therefore, it can be seen that the effect of the adsorption layer is similar to further reducing the micro-gap. It can be seen that the bearing capacity of the thin-film lubricating bearings is greatly increased. However, it should also be noted that the effect of the adsorption layer changes the temperature field, the gap decreases, the flow of lubricant decreases, the amount of heat removed by the lubricant decreases, and the temperature increase increases, which in turn changes the characteristics of the lubricant. Velocity analysis of fluids is a key issue in flow field analysis. The results of this study can be extended to other flow field analyses. The following conclusions are based on calculations and simplified analysis for reference: 1) This study is applicable to flow analysis under small gaps. , such as capillary flow, nanogap flow, etc. Its characteristic is that the wall effect can not be ignored, so when the gap is small to a certain extent, it will not be able to flow or require a large pressure difference. 2) The temperature change in the flow field analysis is related to the velocity of the fluid. Because the strong adsorption of the wall causes the velocity gradient to change and form a large velocity gradient, this study also provides a reference for the temperature field analysis. 3) Due to large velocity gradients, lubricant thinning issues must be considered and this study will provide data for thinning studies.
