摘要

右旋螺旋桨和左旋螺旋桨在同方向旋转时的平移方向是相反的。对映体也可能出现同样的现象。本文使用 3D 打印机制作了对映体八面体和四面体，并在液体介质中旋转。旋转轴是通过求解形状张量的特征值问题确定的，而形状张量是这些多面体形状的流体力学特征。该模型表现出类似螺旋桨的运动，表明有可能分离对映体。

Chiral separation of enantiomorphic objects by rotation in a fluid

Right- and left-handed propellers translate in opposite directions when rotated in the same direction. The same phenomenon may occur with enantiomorphic objects. In this paper, enantiomorphic octahedrons and tetrahedrons were fabricated using a 3D printer and rotated in a liquid medium. The rotation axis was determined by solving an eigenvalue problem for the shape tensor that hydrodynamically characterizes the shape of these polyhedrons. The model exhibited propeller-like motion, indicating the possibility of separating enantiomorphic objects.
