... model predicts extremely high and unrealistic values of traction coefficient, especially under near pure rolling conditions where thermal effect is negligible. Therefore, an EHL model incorporating the effect of limiting shear stress and the associated wall slip phenomenon is presented herein. Unlike...

... 06 2006 machine bearings sliding friction slip lubrication wall slip lubrication low friction In classical fluid dynamics, it is usually assumed that there is no slip of the velocity of fluid over a solid wall. This is known as the no-slip boundary condition and has been...

...C. W. Wu; G. J. Ma; H. S. Sun A mathematical programming solution based on finite element method is used to analyze wall slip of viscoplastic lubrication in a metal-rolling inlet zone. Slip velocity can be directly obtained by parametric quadratic programming without an iterative process between...
