Abstract
The non-Newtonian viscosity of a dilute gas of hard spheres under uniform shear flow is obtained by means of a Boltzmann–Monte Carlo simulation method. The influence of initial conditions is analyzed. The results are compared with exact solutions of the Boltzmann and the Bhatnagar-Gross-Krook equations. The agreement is shown to be fairly good over a wide range of shear rates.Keywords
