Figure 4. Fourier analysis of velocity for quadrupolar and dipolar distortions.

Figure 4

(a) Radial Inline graphic and (b) azimuthal Inline graphic coefficients for LCEO flows triggered by a quadrupolar director pattern, Fig. 2b; (c) velocity field reconstructed with the three harmonics that show a close similarity to the experimental data in Fig. 2b; (df), the same, but for a sphere with a dipolar director and LCEO pumping, compare with Fig. 2f. Particle diameter 2a=50 μm.
