Effects of surface viscosities on the motion of a droplet enclosing a translating particle
Ali Gürbüz, Hervé Nganguia, Guangpu Zhu +3
We investigate the influence of interfacial rheology on the motion of a compound particle consisting of a viscous droplet enclosing a translating rigid particle in the Stokes flow…

Collinear Swimming of a Squirmer Pair in Newtonian and Shear-Thinning Fluids
Chih-Tang Liao, Ali Gürbüz, Victor Bueno Garcia +3
Pairwise hydrodynamic interactions of microswimmers form the fundamental building blocks for understanding their more complex collective behaviors. In this work, we revisit the can…

Propulsion of a three-sphere micro-robot in a porous medium
Chih-Tang Liao, Andrew Lemus, Ali Gürbüz +3
Microorganisms and synthetic microswimmers often encounter complex environments consisting of networks of obstacles embedded into viscous fluids. Such settings include biological m…
