Lubricant Shear Thinning Analysis of Engine Journal Bearings (original) (raw)

Tribology Transactions, 2001

Abstract

The high shearing stresses encountered in the modern engine bearing lubricant film lead to significant drop in viscosity of multigrade oils and affect the values of film thickness, power loss and oil flow significantly in the engine bearings. The popular mobility method is incapable to incorporate shear thinning, and time-consuming numerical schemes are not readily acceptable in industry. The present
