"Dancing to Turbulence: Transitions Between Flow States in Confined Active Nematics"

ABSTRACT


Biological active fluids, such as dense suspensions of swimming bacteria, are fluid mixtures whose components are alive and motile. These suspensions differ from passive fluids since biochemical activity continuously pushes them out of equilibrium, leading to spontaneous collective flows at scales larger than the individual components. While these spontaneous flows are typically disorderly (and sometimes referred to as active turbulence), they also have the potential for novel applications. This talk will describe the transitions between steady, ordered active flows and disorderly active turbulence within confining microchannels. The knowledge gained from studying such “living” flows within confining channels is essential for future designs of hybrid bio-mechanical microfluidic devices that have the potential to work with biological fluids, rather than against them.
