Spatio-Temporal Pattern of Turbulence in a Fluid Moving between 2 Plates

Caption

Spatio-temporal pattern of turbulence in a fluid moving between two plates is pictured. At low speeds (top) turbulence is strictly confined to localized patches. At high speeds (bottom) on the other hand flows are turbulent throughout. In the paper we describe how turbulence is transformed from a local excitation into an expanding state that aggressively invades its surrounding.
