TL;DR: Heidenreich et al. as mentioned in this paper derived a fourth-order continuum theory capable of reproducing mesoscale turbulence in a three-dimensional suspension of microswimmers, which includes hydrodynamic interactions on both small length scales (polar alignment of neighboring swimmers) and large length scales, where the solvent flow interacts with the order parameter field.

TL;DR: In this paper, a combination of continuum theory and experiments on a bacterial suspension is used to show how artificial obstacles guide the flow profile and reorganize topological defects, which enables the design of bacterial vortex lattices with tunable properties.

TL;DR: In this article, the influence of orienting external fields on pattern formation, particularly mesoscale turbulence, in microswimmer suspensions was studied. But the model was not extended to include an external field that exerts an aligning torque on the swimmers, leading to strongly asymmetric, traveling stripe patterns.

TL;DR: In this paper, the authors investigate the occurrence of shear banding in nematogenic fluids under planar Couette flow, based on mesoscopic dynamical equations for the orientational order parameter and the shear stress.
