The coupled nonlinear dynamics of rotary motor ensembles and an embedding fluid medium are simulated on the basis of Navier-Stokes equations. The model description considers space-dependent rotation of motors and a spatially inhomogeneous motor distribution as well as spatial fluctuations in molecular properties. The mutual influence of motor rotations and fluid dynamics as well as spatial inhomogeneities of their molecular properties are self-consistently included. Space-time simulations visualize the complex interplay between the fluid dynamics and motor rotation and show that the dynamic coupling to the environment via the velocity field as well as the spatial inhomogeneity and distribution of rotors determines the overall behavior of the motor complex. Depending on the initial molecular distribution, rotation frequency, and fluid dynamics a spatial self-organization or a chaotic behavior may arise.
基于纳维-斯托克斯方程，对旋转电机组件与嵌入流体介质的耦合非线性动力学进行了模拟。该模型描述考虑了电机的空间相关旋转、空间非均匀的电机分布以及分子特性的空间波动。电机旋转与流体动力学之间的相互影响以及它们分子特性的空间非均匀性被自洽地纳入其中。时空模拟可视化了流体动力学与电机旋转之间的复杂相互作用，并表明通过速度场与环境的动态耦合以及转子的空间非均匀性和分布决定了电机复合体的整体行为。根据初始分子分布、旋转频率和流体动力学，可能会出现空间自组织或混沌行为。
