Abstract: The hydrodynamic interactions among microorganisms and the surrounding boundary give rise to novel emergent behaviors at macroscopic length scales, i.e., self-organization, active turbulence, and bacterial superfluid. In this talk I present a newly proposed model that is both physically effective and computationally efficient in describing hydrodynamic interactions in active fluids. Then we show that our model is essential in predicting two well-known phenomena observed in experiments: bacterial entrapment, and enhanced motility of bacteria in suspensions of macromolecules.
