应用Boltzmann动力学理论，分析了简单剪切流动下能量不均分对颗粒状二元混合物压力和剪切粘度的影响。理论和蒙特卡罗模拟表明，这两个量都表现出非单调的行为与质量比的预测，从以前的理论的基础上均分假设。我们的结果与Alam和Luding最近进行的分子动力学模拟[Granular Matter 4，139（2002）]定性一致。
The Boltzmann kinetic theory is used to analyze the effect of energy nonequipartition on the pressure and the shear viscosity of a granular binary mixture under simple shear flow. Theory and Monte Carlo simulations show that both quantities exhibit anon−monotonicbehaviour with the mass ratio in contrast to the predictions made from previous theories based on the equipartition assumption. Our results agree qualitatively well with recent molecular dynamics simulations performed by Alam and Luding [Granular Matter 4, 139 (2002)].
