Dr. Enkelaida Lushi, Flatiron InstituteDr. Enkelaida Lushi, Flatiron InstituteEwing 336 Conference RoomTitle: Nonlinear concentration patterns and bands in chemotactic active suspensions <br><br> Abstract: In suspensions of microorganisms, pattern formation can arise from the interplay of chemotaxis and the fluid flows collectively-generated by the organisms themselves. Here we investigate the resulting pattern formation in square and elongated domains when the chemo-attractant dynamics is fully coupled to the fluid flows and swimmer motion. Analyses reveal an aggregative instability due to chemotaxis, independent of swimmer shape and type, and a hydrodynamic instability for “pusher” swimmers. Simulations reveal a critical length scale of the swimmer aggregates and this feature e can be utilized to stabilize swimmer concentration patterns into quasi-one-dimensional bands by varying the domain size. These concentration bands transition to traveling pulses under an external chemo-attractant gradient, as observed in experiments with chemotactic bacteria. 11/1/2018 7:30:00 PM11/1/2018 8:30:00 PMFalse
