| Abstract: | The fluid dynamics of sperm motility near both rigid and elastic walls is studied using the immersed boundary method. Simulations
of both single and interacting organisms are presented. In particular, we find that nearby organisms originally undulating
with a 90° phase shift may adjust their relative swimming velocities and phase-lock. Comparisons with previous analytical
results are also discussed. The tendency of a near-wall to attract organisms is demonstrated. |
