Two-dimensional flagellar synchronization in viscoelastic fluids

  title={Two-dimensional flagellar synchronization in viscoelastic fluids},
  author={Gwynn J. Elfring and On Shun Pak and Eric Lauga},
Experimental studies have demonstrated that spermatozoa synchronize their flagella when swimming in close proximity. In a Newtonian fluid, it was shown theoretically that such synchronization arises passively due to hydrodynamic forces between the two swimmers if their waveforms exhibit a front–back geometrical asymmetry. Motivated by the fact that most biological fluids possess a polymeric microstructure, here we address synchronization in a viscoelastic fluid analytically. Using a two… CONTINUE READING
