Representative quantities for the Stokes dynamics of a free–falling sphere (a) and chiral particles (b) in a stagnant fluid. (a) Vertical velocity (red) and drag force (blue) are compared with the reference Stokes values (black). (b) Angular velocities in the body reference frame (green axes in figure 1) for a left–handed (blue) and right–handed (red) chiral particles. Note that here, since the external turbulence forcing is absent, the velocity scale U is undefined; all results are therefore scaled using U_g = (|ρ_p/ρ_f − 1||g|D_eq)^1/2.
