Modelling the Fluid Mechanics of Cilia and Flagella in Reproduction and Development
Cilia and flagella are actively bending slender organelles, performing functions such as motility, feeding and embryonic symmetry breaking. We review the mechanics of viscous-dominated microscale flow, including time-reversal symmetry, drag anisotropy of

Particle motion in Stokes flow near a plane fluid-fluid interface. Part 1. Slender body in a quiescent fluid [PDF]
The present study examines the motion of a slender body in the presence of a plane fluid–fluid interface with an arbitrary viscosity ratio. The fluids are assumed to be at rest at infinity, and the particle is assumed to have an arbitrary orientation ...

Interactions Between Active Matters and Endogenous Fields
This review synthesizes endogenous field information and computational methods in contexts such as cancer, wounds, and biofilms. It organizes NAMs and AAMs by sensing, transmitting, and executing functions, compares their limitations, and from these contrasts proposes design strategies for next‐generation AAMs, offering perspectives to foster ...

Creeping motion of a solid particle inside a spherical elastic cavity. II. Asymmetric motion [PDF]
An analytical method is proposed for computing the low-Reynolds-number hydrodynamic mobility function of a small colloidal particle asymmetrically moving inside a large spherical elastic cavity, the membrane of which is endowed with resistance toward ...

Stokeslet and the Operator Extensions Theory
Summary: Operator version of the stokeslet method in the theory of creeping flow is suggested. The approach is based on the theory of self-adjoint operator extensions in \(L_2\) and in the Pontryagin's space with an indefinite metric. The Stokes flow in two channels connected through a small opening is considered, together with the case of a periodic ...

Integrating the Probe and Singular Sources Methods: II. the Stokes System
ABSTRACT In this paper, an integrated theory of the probe and singular sources methods for an inverse obstacle problem governed by the Stokes system in a bounded domain is developed. The main results consist of the probe method for the Stokes system, the singular sources method by using the notion of the probe method, and the completely integrated ...

Variational Integrators and Fluid‐Structure‐Interaction at Low Reynolds‐Number
Abstract For the special case of incompressible and highly viscous fluids, the interaction with a rigid body can be collected in a damping matrix, relating the velocities and angular velocities of the body with the fluid force and torque. This damping matrix (a.k.a. viscous resistance matrix) depends exclusively on the geometry and needs to be computed

The leading effect of fluid inertia on the motion of rigid bodies at low Reynolds number [PDF]
We investigate the influence of fluid inertia on the motion of a finite assemblage of solid spherical particles in slowly changing uniform flow at small Reynolds number, Re, and moderate Strouhal number, Sl. We show that the first effect of fluid inertia

Eigenfunction Expansions for the Stokes Flow Operators in the Inverted Oblate Coordinate System
When studying axisymmetric particle fluid flows, a scalar function, ψ, is usually employed, which is called a stream function. It serves as a velocity potential and it can be used for the derivation of significant hydrodynamic quantities. The governing equation is a fourth‐order partial differential equation; namely, E4ψ = 0, where E2 is the Stokes ...
