Fig. 3: Predicted spinner angular velocity at increasing Reynolds numbers \({\rm{Re}}\).
From: Emergence of lanes and turbulent-like motion in active spinner fluid

Plots of spinner angular velocity ω for the long-term behavior for a \({\rm{Re}}=0\), b \({\rm{Re}}=0.01\), and c \({\rm{Re}}=0.1\). Yellow regions have counterclockwise (CCW) spinners and blue regions have clockwise (CW) spinners. The black arrows show the direction of fluid flow.
