本文推导了定常库埃特流中气体粘度与剪切速率的关系。粘度是从Bhatnagar-Gross-Krook模型动力学方程的解中找到的，考虑到气体的粘性加热。结果与Naitoh和Ono的计算机分子动力学实验相当吻合。
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 Bhatnagar‐Gross‐Krook 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.
