Summary:

A Penn State, single-pass, capillary high shear viscometer redesigned for use at shear rates up to 106 s1 and viscosity levels as low as 2 cp. is described. The capability of handling the effects of temperature, pressure and kinetic energy changes of Newtonian fluids over a wide range of shear rates and viscosities has been demonstrated by using a series of capillaries of different lengths and diameters. The non-Newtonian characteristics of polymer containing fluids can be obtained with good precision by using the calibrated high-shear viscometer to determine the difference in flow behavior between a Newtonian and a non-Newtonian oil with similar temperature, pressure and kinetic energy corrections.This modified viscometer has been demonstrated with a series of viscosity index improved oils using VI improvers typical of current automotive crankcase lubricants. The viscosity shear behavior of these polymer blends was determined over the range of 102 to 106 s-1 shear rates at 121°C (250°F) and 149°C (300°F)
