From: Modelling bacterial twitching in fluid flows: a CFD-DEM approach

Effect of fluid flow on bacterial twitching behaviour: (a) As the fluid flow increases, the probability of upstream twitching (Red bars) decreases and reaches a minimum and then increases to a maximum and then it decreases again; (b) Time average velocity in upstream and downstream directions; (c) Upstream twitching distance; (d) Number of twitching events.
