Ciliary propulsion, chaotic filtration and a ‘blinking’ stokeslet

Journal of Engineering Mathematics, 1996
The authors discuss the fundamental singularity of Stokes flow in context of applications to locomotion and feeding currents in microorganism. It is reported that the image system for a stokeslet in a rigid plane boundary can be derived by using the Lorentz's mirror image technique or by an appropriate limit of Oseen's solution for a sphere near a ...

A swarm of Stokeslets with interfacial tension

Physics of Fluids, 2001
A formal analogy between sedimenting drops in Stokes flow and a swarm of Stokeslets [Machu et al., J. Fluid Mech. (in press)] is extended to include interfacial tension. Using a cohesive potential, mean curvature is extended as a meaningful quantity off the interface, allowing the boundary-integral formulation to be rewritten in volumetric form.

The unsteady stokeslet and oseenlet

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2000
The unsteady low Reynolds number flow of an incompressible viscous fluid past a singular forcelet is investigated analytically. New fundamental three-dimensional solutions for a concentrated impulsive force are derived for the Stokes and the Oseen equations.

Filter Feeding, Chaotic Filtration, and a Blinking Stokeslet

Theoretical and Computational Fluid Dynamics, 1998
A fluid mechanical model is developed for the filtering mechanism in mussels that enables estimates to be made of the pressure drop through the gill filaments due to (i) latero-frontal filtering cilia, (ii) the lateral (pumping) cilia, and (iii) through the non-ciliated zone of the ventral end of the filament.

Stokeslets and Eddies in Creeping Flow

Annual Review of Fluid Mechanics, 1980
Flow at low Reynolds number Re = pUL//1 is characterized by the small­ ness of representative quantities in the flow, i.e. the density p, the velocity U, and the length L, as well as by large values of the viscosity J.l. If we let Re --+ 0 and neglect the molecular structure of the fluid that is studied in rarefied fluid dynamics as well as the ...

The Method of Regularized Stokeslets

SIAM Journal on Scientific Computing, 2001
This paper presents a numerical method for computing Stokes flows with immersed boundaries and obstacles. The method is based on the smoothing of forces, leading to regularized stokeslets. The resulting expressions give pressure and velocity fields as functions of the forcing.
