Stirring by swimmers in confined microenvironments
We consider the tracer diffusion Drrthat arises from the run-and-tumble motion of low Reynolds number swimmers, such as bacteria. In unbounded dilute suspensions, where dipole swimmers move in uncorrelated runs of length λ, an exact solution showed that Drris independent of λ. Here, we verify this r...
