论文摘要
活性，低雷诺数悬浮液的流体动力模型显示，渐近状态在速度场中具有通用光谱缩放和非高斯（间歇性）波动的出现。当将这些系统推出超出关键活动水平并显示出类似于雷诺数高的数字，惯性湍流时，就会出现这种状态。我们为在活动的临界值中存在这种过渡提供了令人信服的数值和分析证据，并进一步表明最大混乱的状态与这种过渡有关。
A hydrodynamic model of active, low Reynolds number suspensions, shows the emergence of an asymptotic state with a universal spectral scaling and non-Gaussian (intermittent) fluctuations in the velocity field. Such states arise when these systems are pushed beyond a critical level of activity and show features akin to high Reynolds number, inertial turbulence. We provide compelling numerical and analytical evidence for the existence of such a transition at a critical value of activity and further show that the maximally chaotic states are tied to this transition.
