Abstract/OtherAbstract:
We consider the tracer diffusion D_{rr} that arises from the run-and-tumble motion of low Reynolds number swimmers, such as bacteria. Assuming a dilute suspension, where the bacteria move in uncorrelated runs of length λ, we obtain an exact expression for D_{rr} for dipolar swimmers in three dimensions, hence explaining the surprising result that this is independent of λ. We compare D_{rr} to the contribution to tracer diffusion from entrainment.
