Generalised geometric swimming for Stokes flow (2019)
Conference Proceeding
Koens, L., & Lauga, E. (2019). Generalised geometric swimming for Stokes flow. In 72nd Annual Meeting of the APS Division of Fluid Dynamics. Meeting Abstracts

Shapere and Wilczek first demonstrated that the displacement of a microscopic swimmer was related to path integrals over a gauge field. This field is a function of the swimmers configuration and laboratory frame position. For simple 1D swimmers, Stok... Read More about Generalised geometric swimming for Stokes flow.

A Light-Driven Microgel Rotor (2019)
Journal Article
Zhang, H., Koens, L., Lauga, E., Mourran, A., & Möller, M. (2019). A Light-Driven Microgel Rotor. Small, 15(46), Article 1903379. https://doi.org/10.1002/smll.201903379

The current understanding of motility through body shape deformation of micro-organisms and the knowledge of fluid flows at the microscale provides ample examples for mimicry and design of soft microrobots. In this work, a 2D spiral is presented that... Read More about A Light-Driven Microgel Rotor.

Method of regularised stokeslets: Flow analysis and improvement of convergence (2019)
Journal Article
Zhao, B., Lauga, E., & Koens, L. (in press). Method of regularised stokeslets: Flow analysis and improvement of convergence. Physical Review Fluids, 4(8), Article 084104. https://doi.org/10.1103/PhysRevFluids.4.084104

Since their development in 2001, regularised stokeslets have become a popular numerical tool for low-Reynolds number flows since the replacement of a point force by a smoothed blob overcomes many computational difficulties associated with flow singul...

The near and far of a pair of magnetic capillary disks (2019)
Journal Article
Koens, L., Wang, W., Sitti, M., & Lauga, E. (2019). The near and far of a pair of magnetic capillary disks. Soft matter, 15(7), 1497-1507. https://doi.org/10.1039/c8sm02215a

Control on microscopic scales depends critically on our ability to manipulate interactions with different physical fields. The creation of micro-machines therefore requires us to understand how multiple fields, such as surface capillary or electro-ma...
