Electrostatic approaches are successful in explaining the experimentally observed field-induced orientations of the axis with the highest Clausius-Mossotti factor. For conductive or nonconductive, prolate or oblate spheroids, this is always the longest axis when different frequency-dependent dispersions of their effective conductivity along the three principal axes are neglected. Here, it is shown that these orientations correspond to the ‘law of maximum entropy production’ (LMEP) by comparing the axes-ratio dependencies of the torques calculated with the electrostatic approach with the effective conductivity differences between a suspension with field-oriented and randomly oriented objects. At low volume fraction, the obtained conductivity differences, which enter the LMEP, predict almost exactly the torque curves when plotted over axis ratio of the objects. Since the field-induced orientation at constant field strength increases the effective conductivity, the suspension syste...

最大熵产生定律可以描述椭圆形旋转场的诱导方向吗？

静电方法成功地解释了实验观察到的磁场引起的克劳修斯-莫索蒂系数最高的轴的方向。对于导电或不导电的扁长形或扁球形，当忽略其有效电导率沿三个主轴的不同频率相关色散时，它始终是最长的轴。在这里，通过将静电方法计算出的转矩的轴比依存性与磁场定向悬架与随机悬架之间的有效电导率差进行比较，表明这些定向与“最大熵产生定律”（LMEP）相对应。面向对象。在低体积分数下，获得的电导率差异进入LMEP，当绘制对象的轴比时，几乎可以准确预测扭矩曲线。由于在恒定的场强下场感应的取向会增加有效电导率，因此悬架系统会产生较大的振动。
