Abstract
The anomalous viscosity is calculated from a direct solution of the differential equation for the perturbed radial distribution function. The resultant expression for the anomalous viscosity is a fourfold integral which depends parametrically on the velocity gradient. A series expansion of the viscosity in powers of the velocity gradient is divergent, but numerical integration yields a well-behaved non-Newtonian viscosity.
