Nonlinear shear viscosity of a gas
Abstract
This article contains a derivation of the shear rate dependence of the viscosity of a gas in steady Couette flow. The viscosity is found from a solution of the BhatnagarGrossKrook model kinetic equation, taking into account the viscous heating of the gas. The results are in reasonably good agreement with computer molecular dynamic experiments by Naitoh and Ono.
