Journal of Applied Fluid Mechanics, 2016 The instinct system of cilia motion with magnetic field and slip for Jeffrey fluid model in a symmetric channel is examined. The problem of two-dimensional fluid motion in a symmetric channel with ciliated walls is considered.

Designing metachronal waves of cilia
, 2020 On surfaces with many motile cilia, beats of the individual cilia coordinate to form metachronal waves. We present a theoretical framework that connects the dynamics of an individual cilium to the collective dynamics of a ciliary carpet via systematic coarse-graining.

Robust formation of metachronal waves in directional chains of phase oscillators [PDF]
Physical Review E, 2023 Biological systems can rely on collective formation of a metachronal wave in an ensemble of oscillators for locomotion and for fluid transport. We consider one-dimensional chains of phase oscillators with nearest neighbor interactions, connected in a loop and with rotational symmetry, so each oscillator resembles every other oscillator in the chain ...

Magnetic cilia carpets with programmable metachronal waves [PDF]
Nature Communications, 2020 AbstractMetachronal waves commonly exist in natural cilia carpets. These emergent phenomena, which originate from phase differences between neighbouring self-beating cilia, are essential for biological transport processes including locomotion, liquid pumping, feeding, and cell delivery.

Metachronal waves in a chain of rowers with hydrodynamic interactions [PDF]
The European Physical Journal E, 2011 Filaments on the surface of a microorganism such as Paramecium or Ophalina beat highly synchronized and form so-called metachronal waves that travel along the surfaces. In order to study under what principal conditions these waves form, we introduce a chain of beads, called rowers, each periodically driven by an external force on a straight line ...

Emergence of metachronal waves in a chain of symmetrically beating filaments [PDF]
Physical Review ResearchRecent experiments show that metachronal waves (MCWs) can emerge from a chain of symmetrically beating nematodes aligned at the edge of sessile droplets. Our study, employing a coupled elastohydrodynamic model of active filaments, elucidates that a misalignment caused by a tilt against the bounding wall disrupts the synchronization and generates a ...

Spontaneous Creation of Macroscopic Flow and Metachronal Waves in an Array of Cilia [PDF]
Biophysical Journal, 2006 Cells or bacteria carrying cilia on their surface show many striking features : alignment of cilia in an array, two-phase asymmetric beating for each cilium, coordination between cilia and existence of metachronal waves with a constant phase difference between two adjacent cilia.

Why antiplectic metachronal cilia waves are optimal to transport bronchial mucus [PDF]
Physical Review E, 2019 The coordinated beating of epithelial cilia in human lungs is a fascinating problem from the hydrodynamics perspective. The phase lag between neighboring cilia is able to generate collective cilia motions, known as metachronal waves. Different kinds of waves can occur, antiplectic or symplectic, depending on the direction of the wave with respect to ...

Metachronal waves in the flagellar beating ofVolvoxand their hydrodynamic origin [PDF]
Journal of The Royal Society Interface, 2015 Groups of eukaryotic cilia and flagella are capable of coordinating their beating over large scales, routinely exhibiting collective dynamics in the form of metachronal waves. The origin of this behaviour—possibly influenced by both mechanical interactions and direct biological regulation—is poorly understood, in large part due to a lack of ...
