Optimal swimmer can be puller, pusher, or neutral depending on the shape
Abdallah Daddi-Moussa-Ider, Babak Nasouri, Andrej Vilfan +1
The ability of microswimmers to deploy optimal propulsion strategies is of paramount importance for their locomotory performance and survival at low Reynolds numbers. Although for…
Minimum Dissipation Theorem for Microswimmers
Babak Nasouri, Andrej Vilfan, Ramin Golestanian
We derive a theorem for the lower bound on the energy dissipation rate by a rigid surface-driven active microswimmer of arbitrary shape in a fluid at low Reynolds number. We show t…
Exact axisymmetric interaction of phoretically active Janus particles
Babak Nasouri, Ramin Golestanian
We study the axisymmetric interaction of two chemically active Janus particles. By relying on the linearity of the field equations and symmetry arguments, we derive a generic solut…
Exact phoretic interaction of two chemically-active particles
Babak Nasouri, Ramin Golestanian
We study the nonequilibrium interaction of two isotropic chemically-active particles taking into account the exact near-field chemical interactions as well as hydrodynamic interact…
Efficiency limits of the three-sphere swimmer
Babak Nasouri, Andrej Vilfan, Ramin Golestanian
We consider a swimmer consisting of a collinear assembly of three spheres connected by two slender rods. This swimmer can propel itself forward by varying the lengths of the rods i…
Two-sphere swimmers in viscoelastic fluids
Charu Datt, Babak Nasouri, Gwynn J. Elfring
We examine swimmers comprising of two rigid spheres which oscillate periodically along their axis of symmetry, considering both when the oscillation is in phase and anti-phase, and…
Dynamics of poroelastocapillary rise
Babak Nasouri, Benjamin Thorne, Gwynn J. Elfring
A wetting liquid is driven through a thin gap due to surface tension and when the gap boundaries are elastic, the liquid deforms the gap as it rises. But when the fluid boundaries…
Higher-order force moments of active particles
Babak Nasouri, Gwynn J. Elfring
Active particles moving through fluids generate disturbance flows due to their activity. For simplicity, the induced flow field is often modeled by the leading terms in a far-field…
An elastic two-sphere swimmer in Stokes flow
Babak Nasouri, Aditi Khot, Gwynn J. Elfring
Swimming at low Reynolds number in Newtonian fluids is only possible through non-reciprocal body deformations due to the kinematic reversibility of the Stokes equations. We conside…
Hydrodynamic interactions of cilia on a spherical body
Babak Nasouri, Gwynn J. Elfring
Microorganisms develop coordinated beating patterns on surfaces lined with cilia known as metachronal waves. For a chain of cilia attached to a flat ciliate, it has been shown that…
