Quartz Crystal Microbalance impedance of discrete adsorbates with lubricated contact
Alexander M. Leshansky, Boris Y. Rubinstein, Marta Sadowska +1
We present a thorough theoretical investigation of the shear force exerted on a horizontal plate undergoing fast (MHz range) longitudinal oscillations in presence of a spherical pa…
Slow linear shear flow past discrete particles adhered to a plane wall
Itzhak Fouxon, Alexander M. Leshansky
Linear shear flow bounded by a plane wall is an idealization that occurs in microfluidic devices and many other applications. Perfect plane approximation neglects surface irregular…
Excess shear force exerted on oscillating plate due to a nearby particle
Itzhak Fouxon, Boris Rubinstein, Alexander M. Leshansky
In the present paper we theoretically study the shear force exerted on an infinite horizontal plane undergoing fast lateral oscillations in presence of a rigid particle suspended i…
Lamb-type solution and properties of unsteady Stokes equations
Itzhak Fouxon, Alexander Leshansky, Boris Rubinstein +1
We derive the general solution of the unsteady Stokes equations for an unbounded fluid in spherical polar coordinates, in both time and frequency domains. The solution is an expans…
The effect of a wall on the interaction of two spheres in shear flow: Batchelor-Green theory revisited
Itzhak Fouxon, Boris Rubinstein, Zhouyang Ge +2
The seminal Batchelor-Green's (BG) theory on the hydrodynamic interaction of two spherical particles of radii a suspended in a viscous shear flow neglects the effect of the boundar…
Unidirectional propulsion of planar magnetic nanomachines
Kevin-Joshua Cohen, Boris Y. Rubinstein, Oded Kenneth +1
Steering of magnetic nano-/microhelices by a rotating magnetic field is considered as a promising technique for controlled navigation of tiny objects through viscous fluidic enviro…
Integral representation of channel flow with interacting particles
Itzhak Fouxon, Zhouyang Ge, Luca Brandt +1
We construct a boundary integral representation for the low-Reynolds-number flow in a channel in the presence of freely-suspended particles (or droplets) of arbitrary size and shap…
The role of symmetry in driven propulsion at low Reynolds number
Johannes Sachs, Konstantin I. Morozov, Oded Kenneth +4
We theoretically and experimentally investigate low-Reynolds-number propulsion of geometrically achiral planar objects that possess a dipole moment and that are driven by a rotatin…
Impact of turbulence on the stratified flow around small particles
Itzhak Fouxon, Alexander Leshansky
We study the turbulent flow of the density-stratified fluid around a small translating (either passively or self-propelled) particle. It was found recently [A. M. Ardekani and R. S…
Do small swimmers mix the ocean?
A. M. Leshansky, L. M. Pismen
In this communication we address some hydrodynamic aspects of recently revisited drift mechanism of biogenic mixing in the ocean (Katija and Dabiri, Nature vol. 460, pp. 624-626, 2…
Surface tank-treading: propulsion of Purcell's toroidal swimmer
Alexander Leshansky, Oded Kenneth
In this work we address the "smoking ring" propulsion technique, originally proposed by E. M. Purcell. We first consider self-locomotion of a doughnut-shaped swimmer powered by sur…
Comment on "Self-Running Droplet: Emergence of Regular Motion from Nonequilibrium Noise"
V. Berejnov, A. Leshansky
In a recent Letter (Y. Sumino et al., PRL 94, 068301 (2005)) a spontaneous motion of an oil droplet in the surrounding aqueous media along a glass surface was reported. The authors…
