Bio-inspired control model for snake locomotion based on Cosserat beam theory
Eliot Thys, Frédéric Boyer, Yacine Chitour +4
This paper revisits from a mathematical perspective the modeling of locomotion in snake-like bodies in fluid environement as given in \cite{boyer2010poincare} and \cite{boyer2011ma…
The Stokes resistance of an arbitrary particle: a classification of hydrodynamic symmetries
Clément Moreau
The linearity of the Stokes equations organises the hydrodynamic response of a rigid particle into a hierarchy of resistance operators, coupling successive truncations of the ambie…
The hydrodynamic Euler-elastica: shape transitions in the dynamical buckling of elastic filaments in Stokes flow
Clément Moreau, Laetitia Giraldi, Hermes Bloomfield-Gadêlha
The buckling of elastic filaments in viscous fluids, ubiquitous in biological systems like flagella, microtubules, and DNA, has long been described by the static Euler-elastica. Ye…
Bending-compression coupling in extensible slender microswimmers
Kenta Ishimoto, Johann Herault, Clément Moreau
Undulatory slender objects have been a central theme in the hydrodynamics of swimming at low Reynolds number, where the slender body is usually assumed to be inextensible, although…
The N-link model for slender rods in a viscous fluid: well-posedness and convergence to classical elastohydrodynamics equations
Clément Moreau, François Alouges, Aline Lefebvre-Lepot +1
Flexible fibers at the microscopic scale, such as flagella and cilia, play essential roles in biological and synthetic systems. The dynamics of these slender filaments in viscous f…
Robust undulatory locomotion via neuromechanical adjustments in a dissipative medium
Kenta Ishimoto, Clément Moreau, Johann Herault
Dissipative environments are ubiquitous in nature, from microscopic swimmers in low-Reynolds-number fluids to macroscopic animals in frictional media. In this study, motivated by v…
Minimal design of a synthetic cilium
Clément Moreau, Benjamin J. Walker, Rebecca N. Poon +4
We study a slender filament beating in a viscous fluid with novel curvature-dependent bending stiffness. Our numerical and experimental investigations reveal that such differential…
Odd elastohydrodynamics: non-reciprocal living material in a viscous fluid
Kenta Ishimoto, Clément Moreau, Kento Yasuda
Motility is a fundamental feature of living matter, encompassing single cells and collective behavior. Such living systems are characterized by non-conservativity of energy and a l…
Generalised Jeffery's equations for rapidly spinning particles. Part 1: Spheroids
Mohit P. Dalwadi, Clément Moreau, Eamonn A. Gaffney +2
The observed behaviour of passive objects in simple flows can be surprisingly intricate, and is complicated further by object activity. Inspired by the motility of bacterial swimme…
Generalised Jeffery's equations for rapidly spinning particles. Part 2: Helicoidal objects with chirality
Mohit P. Dalwadi, Clément Moreau, Eamonn A. Gaffney +2
In this two-part study, we investigate the motion of rigid, active objects in shear Stokes flow, focusing on bodies that induce rapid rotation as part of their activity. In Part 2,…
Emergent rheotaxis of shape-changing swimmers in Poiseuille flow
Benjamin J. Walker, Kenta Ishimoto, Clément Moreau +2
A simple model for the motion of shape-changing swimmers in Poiseuille flow was recently proposed and numerically explored by Omori et al. (2022). These explorations hinted that a…
The effects of rapid yawing on simple swimmer models and planar Jeffery's orbits
Benjamin J. Walker, Kenta Ishimoto, Eamonn A. Gaffney +2
Over a sufficiently long period of time, or from an appropriate distance, the motion of many swimmers can appear smooth, with their trajectories appearing almost ballistic in natur…
Self-organized swimming with odd elasticity
Kenta Ishimoto, Clément Moreau, Kento Yasuda
We theoretically investigate self-oscillating waves of an active material, which have recently been introduced as a non-symmetric part of the elastic moduli, termed odd elasticity.…
Control and controllability of microswimmers by a shearing flow
Clément Moreau, Kenta Ishimoto, Eamonn A. Gaffney +1
With the continuing rapid development of artificial microrobots and active particles, questions of microswimmer guidance and control are becoming ever more relevant and prevalent.…
The control of particles in the Stokes limit
Benjamin J. Walker, Kenta Ishimoto, Eamonn A. Gaffney +1
There are numerous ways to control objects in the Stokes regime, with microscale examples ranging from the use of optical tweezers to the application of external magnetic fields. I…
State-constrained controllability of linear reaction-diffusion systems
Pierre Lissy, Clément Moreau
We study the controllability of a coupled system of linear parabolic equations, with non-negativity constraint on the state. We establish two results of controllability to trajecto…
Necessary conditions for local controllability of a particular class of systems with two scalar controls
Laetitia Giraldi, Pierre Lissy, Clément Moreau +1
We consider affine control systems with two scalar controls, such that one control vector field vanishes at an equilibrium state. We state two necessary conditions of local control…
The asymptotic coarse-graining formulation of slender-rods, bio-filaments and flagella
Clément Moreau, Laetitia Giraldi, Hermes Gadêlha
The inertialess fluid-structure interactions of active and passive inextensible filaments and slender- rods are ubiquitous in nature, from the dynamics of semi-flexible polymers an…
Controllability of a bent 3-link magnetic microswimmer
Laetitia Giraldi, Pierre Lissy, Clément Moreau +1
- In this paper, we focus on a variant of a 3-link magnetic microswimmer which consists of three rigid magnetized segments connected by two torsional springs. In particular, we ass…
