Direct measurement of the flow field around swimming microorganisms [PDF]
, 2010 Swimming microorganisms create flows that influence their mutual interactions and modify the rheology of their suspensions. While extensively studied theoretically, these flows have not been measured in detail around any freely-swimming microorganism. We

Image systems for regularised Stokeslets at walls and free surfaces
European Journal of Mechanics - B/Fluids, 2023 The authors discuss the system of stationary Stokes equations and its singular solutions, stokeslets. The method of regularised stokeslets is developed. It consists in replacing a sum over singular point elements by one over finite distributed sources. The authors apply the image method for regularised stokeslets in the case of plane no-slip walls and ...

Regularized Stokeslet segments [PDF]
Journal of Computational Physics, 2018 We present a variation of the method of regularized Stokeslet (MRS) specialized for the case of forces and torques distributed over filaments in three dimensions. The new formulation is based on the exact solution of Stokes equation generated by a linear continuous distribution of regularized forces along a line segment.

Hydromechanics of low-Reynolds-number flow. Part 5. Motion of a slender torus [PDF]
, 1979 In order to elucidate the general Stokes flow characteristics present for slender bodies of finite centre-line curvature the singularity method for Stokes flow has been employed to construct solutions to the flow past a slender torus. The symmetry of the

An Elastic Collision Model for Impulsive Jumping by Small Planktonic Organisms
Fluids, 2020 Many small marine planktonic organisms converge on similar propulsion mechanisms that involve impulsively generated viscous wake vortex rings, and small-scale fluid physics is key to mechanistically understanding the adaptive values of this important ...

Brownian motion near a partial-slip boundary: A local probe of the no-slip condition [PDF]
, 2005 Motivated by experimental evidence of violations of the no-slip boundary condition for liquid flow in micron-scale geometries, we propose a simple, complementary experimental technique that has certain advantages over previous studies. Instead of relying

A boundary element regularised Stokeslet method applied to cilia and flagella-driven flow [PDF]
, 2009 A boundary element implementation of the regularised Stokeslet method of Cortez is applied to cilia and flagella-driven flows in biology. Previously-published approaches implicitly combine the force discretisation and the numerical quadrature used to ...

Hydrodynamic Coupling of Two Brownian Spheres to a Planar Surface [PDF]
, 2000 We describe direct imaging measurements of the collective and relative diffusion of two colloidal spheres near a flat plate. The bounding surface modifies the spheres' dynamics, even at separations of tens of radii.
