Filament mechanics in a half-space via regularised Stokeslet segments [PDF]
Journal of Fluid Mechanics, 2019 We present a generalisation of efficient numerical frameworks for modelling fluid–filament interactions via the discretisation of a recently developed, non-local integral equation formulation to incorporate regularised Stokeslets with half-space boundary conditions, as motivated by the importance of confining geometries in many applications. We proceed

The regularized Stokeslets method applied to the three-sphere swimmer model [PDF]
Physics of Fluids, 2021 We investigate the applicability of the Method of Regularized Stokeslets (MRS) in the simulation of micro-swimmers at low Reynolds number. The chosen model for the study is the well-known three linked sphere swimmer. We compare our results with the lattice Boltzmann method, multiparticle collision dynamics, a numerical solution of the Oseen tensor ...

Soft Bio‐Microrobots: Toward Biomedical Applications
Advanced Intelligent Systems, Volume 6, Issue 2, February 2024.Soft bio‐microrobots are created with designs inspired by living creatures or utilizing motile microorganisms or cells. Their compliant and flexible bodies enable them to adapt to intricate environments. This review presents a summary of the design principles, energy sources, and biomedical applications of soft bio‐microrobots. The challenges that must

Anomalous Long-Ranged Influence of an Inclusion in Momentum-Conserving Active Fluids
Physical Review XWe show that an inclusion placed inside a dilute Stokesian suspension of microswimmers induces power-law number-density modulations and flows. These take a different form depending on whether the inclusion is held fixed by an external force—for example ...

Physics of Rheologically-Enhanced Propulsion: Different Strokes in Generalized Stokes [PDF]
, 2013 Shear-thinning is an important rheological property of many biological fluids, such as mucus, whereby the apparent viscosity of the fluid decreases with shear.

Generic flow profiles induced by a beating cilium
, 2012 We describe a multipole expansion for the low Reynolds number fluid flows generated by a localized source embedded in a plane with a no-slip boundary condition.

Chaotic particle dynamics in viscous flows: The three-particle Stokeslet problem [PDF]
Physical Review E, 1997 It is well known, that the dynamics of small particles moving in a viscous fluid is strongly influenced by the long-range hydrodynamical interaction between them. Motion at high viscosity is usually treated by means of the Stokes equations, which are linear and instantaneous.

Polarized cortical tension drives zebrafish epiboly movements [PDF]
, 2016 The principles underlying the biomechanics of morphogenesis are largely unknown. Epiboly is an essential embryonic event in which three tissues coordinate to direct the expansion of the blastoderm.

Adapting the Teubner reciprocal relations for stokeslet objects
, 2019 Self-propelled colloidal swimmers move by pushing the adjacent fluid backwards. The resulting motion of an asymmetric body depends on the profile of pushing velocity over its surface. We describe a method of predicting the motion arising from arbitrary velocity profiles over a given body shape, using a discrete-source "stokeslet" representation.

, 2012 We investigate the response of a dense monodisperse quasi-two-dimensional (q2D) colloid suspension when a particle is dragged by a constant velocity optical trap.
