Orientation dynamics of chiral particles in turbulence

Particles that break their own mirror symmetry generally have coupled rotational-translation dynamics. Here we will discuss the dynamics of such chiral particles in turbulent Taylor-Couette flows with Reynolds numbers up to 10⁵. We experimentally track the location and orientation of the inertial chiral particles (Stokes number ~ 10³) and obtain statistics on the coupling between the particle rotation and the particle velocity. Based on their rotation-translation coupling dynamics we can reveal the handedness (left or right) of the particles.
