Beating patterns of filaments in viscoelastic fluids
Henry C. Fu, Charles W. Wolgemuth, Thomas R. Powers
Many swimming microorganisms, such as bacteria and sperm, use flexible flagella to move through viscoelastic media in their natural environments. In this paper we address the effec…
Theory of swimming filaments in viscoelastic media
Henry C. Fu, Thomas R. Powers, Charles W. Wolgemuth
Motivated by the swimming of sperm in the non-Newtonian fluids of the female mammalian reproductive tract, we examine the swimming of filaments in the nonlinear viscoelastic Upper…
Dynamic supercoiling bifurcations of growing elastic filaments
Charles W. Wolgemuth, Raymond E. Goldstein, Thomas R. Powers
Certain bacteria form filamentous colonies when the cells fail to separate after dividing. In Bacillus subtilis, Bacillus thermus, and cyanobacteria, the filaments can wrap into co…
Twirling and Whirling: Viscous Dynamics of Rotating Elastica
Charles W. Wolgemuth, Thomas R. Powers, Raymond E. Goldstein
Motivated by diverse phenomena in cellular biophysics, including bacterial flagellar motion and DNA transcription and replication, we study the overdamped nonlinear dynamics of a r…
