摘要：

In this paper, the effect of the asymmetrical electric double layers of two friction surfaces on the pressure distribution in hydrodynamic lubrication regime is discussed. Based on the origin of the streaming potential, a formula to calculate the streaming potential gradient in the lubrication regime is derived. Then, the modified Reynolds equation with considering the asymmetrical electric double layers is used in the numerical analysis. The analysis results show that the asymmetrical electric double layers lead to a significant increase of the pressure when the lubricating film is very thin (below 100 nm). Overall, the larger the sum of the two zeta potentials, the larger the pressure increment is.
