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…

Self-diffusiophoretic propulsion of a spheroidal particle in a shear-thinning fluid
Guangpu Zhu, Brandon van Gogh, Lailai Zhu +2
Shear-thinning viscosity is a non-Newtonian behaviour that active particles often encounter in biological fluids such as blood and mucus. The fundamental question of how this ubiqu…
