Neuromechanical Mechanisms of Gait Adaptation in C. elegans: Relative Roles of Neural and Mechanical Coupling
Carter L. Johnson, Timothy J. Lewis, Robert D. Guy
Understanding principles of neurolocomotion requires the synthesis of neural activity, sensory feedback, and biomechanics. The nematode \textit{C. elegans} is an ideal model organi…
Polymer stress growth in viscoelastic fluids in oscillating extensional flows with applications to micro-organism locomotion
Becca Thomases, Robert D. Guy
Simulations of undulatory swimming in viscoelastic fluids with large amplitude gaits show concentration of polymer elastic stress at the tips of the swimmers.We use a series of rel…
Orientation dependent elastic stress concentration at tips of slender objects translating in viscoelastic fluids
Chuanbin Li, Becca Thomases, Robert D. Guy
Elastic stress concentration at tips of long slender objects moving in viscoelastic fluids has been observed in numerical simulations, but despite the prevalence of flagellated mot…
Self-organized mechano-chemical dynamics in amoeboid locomotion of Physarum fragments
Shun Zhang, Robert D. Guy, Juan C. Lasheras +1
The aim of this work is to quantify the spatio-temporal dynamics of flow-driven amoeboid locomotion in small (100 m) fragments of the true slime mold \phys {\it polycephal…
Scalable smoothing strategies for a geometric multigrid method for the immersed boundary equations
Amneet Pal Singh Bhalla, Matthew G. Knepley, Mark F. Adams +2
The immersed boundary (IB) method is a widely used approach to simulating fluid-structure interaction (FSI). Although explicit versions of the IB method can suffer from severe time…
The role of body flexibility in stroke enhancements for finite-length undulatory swimmers in viscoelastic fluids
Becca Thomases, Robert D. Guy
The role of passive body dynamics on the kinematics of swimming micro-organisms in complex fluids is investigated. Asymptotic analysis of small amplitude motions of a finite-length…
