“…20,39,42,45,49–55 Experiments in the annulus geometry 46,47 and lane configurations 44 demonstrate that confinement can tame this turbulence to generate ordered flows. However, despite these experiments and previous theoretical investigations of active nematics confined in channels, 24,28,37,43,44,56–58 disks, 45,46,59,60 and annulus geometries, 37,46,47,61,62 the influence of channel curvature and finite channel length on emergent behaviors is yet to be studied in detail.…”
