Modeling of the dynamics of autonomous catalytic nanomotors using the method of regularized stokeslets
… accurately captured by the method of Regularized Stokeslets. We also account for solid-frictional forces and torques from the substrate, as prescribed by an established velocity-dependent friction model for micro/nanoscale friction. To explain random deviations, the Brownian fluctuations are …

Novel Bioinspired Pumping Models for Microscale Flow Transport
… In this study, both theoretical analysis and Stokeslets-meshfree computational methods are used to solve for the 2D and 3D viscous flow transport in several micro-geometries (tubes, channels and networks) with prescribed moving wall contractions. The derived theoretical analysis is based on …

A novel boundary element method for low Reynolds number external flow of biological fluid dynamics
… The other methods are: representations using stokeslets (that suffer from Stokes' paradox giving an unbounded velocity); Lamb's (Lamb, 1932) treatment; Yano and Kieda's Oseen flow treatment (Yano & Kieda, 1980); and the matched asymptotic formulations of Kaplun (Kaplun & Lagerstrom, 1957) and …

Dynamic and structural basis of complex behaviour in a ciliated unicellular organism
… minimal model based on the superposition of four stokeslets which captures the key features of the fluid profile while remaining computationally scalable. We then investigate how the presence of a nearby boundary alters this organism’s behaviour. Leveraging electron and expansion microscopy …

A computational framework for the large scale simulation of the dynamics of highly flexible filaments in a viscous flow
… bodies can be approximated by a distribution of Stokeslets. We use GPU resources to solve the dense system generated by the fluid model and push the scale to a cloud of 𝑂(500) flexible filaments. Additionally, to address the numerical instabilities observed as filaments come close to each other, …
