Numerical Study of the Effect of Lip Surface Roughness on Lubrication of Radial Shaft Seals with a Simple Sinusoidal Model

The effect of lip surface microtopography on lubrication of radial shaft seals is studied numerically. Numerical analysis of hydrodynamic flow at the lip is conducted with a simple sinusoidal wave as a lip surface asperity model. In order to understand the effects of lip surface microtopography on m...
