研究了剪切硬球悬浮液的速度概率分布函数(PDF)。正如我们在Stokes流模拟中观察到的和用我们的单粒子理论解释的那样，这些PDF可以显示出与麦克斯韦-玻尔兹曼分布的明显偏差。PDFs在零速度附近是对称的，在超过六个数量级的概率上表现出高斯核和指数尾。根据理论和模拟数据的良好一致性，我们证明了分布函数与剪切速率、颗粒体积浓度以及流体粘度有关。

英文摘要：
We investigate velocity probability distribution functions (PDF) of sheared hard-sphere suspensions. As observed in our Stokes flow simulations and explained by our single-particle theory, these PDFs can show pronounced deviations from a Maxwell-Boltzmann distribution. The PDFs are symmetric around zero velocity and show a Gaussian core and exponential tails over more than six orders of magnitude of probability. Following the excellent agreement of our theory and simulation data, we demonstrate that the distribution functions scale with the shear rate, the particle volume concentration, as well as the fluid viscosity.
