Imaging the emergence of bacterial turbulence: Phase diagram and transition kinetics - 1 views

cferiante on 23 May 22"Collective motions of biological systems such as bird flocks, fish schools, and bacterial swarms are the most vivid examples of the emergent behaviors of active matter (1). While moving independently at low density, self-propelled units in active matter can move collectively at high density, giving rise to coherent flows at length scales much larger than the size of individual units. In bacterial suspensions, these coherent flows exhibit a chaotic pattern of intermittent vortices and jets, reminiscent of turbulent flows at high Reynolds numbers. Hence, the flows induced by bacterial collective swimming are also known as active or bacterial turbulence (2-5)."
