FIG. 7.

Demonstration of the concept of tunable ROT-ICEO by solving $d(\rho \prime \hspace{0.17em}\text{cos}\hspace{0.17em}\theta \prime ,\rho \prime \hspace{0.17em}\text{sin}\hspace{0.17em}\theta \prime )/\mathit{d}\mathit{t}={\mathit{u}}_{\mathit{\theta }\prime }$ numerically with the arrows, line, the left and right bar indicating $⟨{\mathit{u}}_{\mathit{\rho }\prime }⟩$, FSL, the particle transient velocity and $\left|{\mathit{u}}_{\mathit{\rho }\prime }\right|$, respectively.(The verification experiments refer to supporting movie 5.)
