Inertial torque on a squirmer
F. Candelier, J. Qiu, L. Zhao +2
A small spheroid settling in a quiescent fluid experiences an inertial torque that aligns it so that it settles with its broad side first. Here we show that an active particle expe…
Hydrodynamic force on a small squirmer moving with a time-dependent velocity at small Reynolds numbers
T. Redaelli, F. Candelier, R. Mehaddi +2
We calculate the hydrodynamic force on a small spherical, unsteady squirmer moving with a time-dependent velocity in a fluid at rest, taking into account convective and unsteady fl…
Second-order inertial forces and torques on a sphere in a viscous steady linear flow
Fabien Candelier, Rabah Mehaddi, Bernhard Mehlig +1
We compute the full set of second-order inertial corrections to the instantaneous force and torque acting on a small spherical rigid particle moving unsteadily in a general steady…
Unsteady and inertial dynamics of an active particle in a fluid
T. Redaelli, F. Candelier, R. Mehaddi +1
It is well known that the reversibility of Stokes flow makes it difficult for small microorganisms to swim. Inertial effects break this reversibility, allowing new mechanisms of pr…
Lord Kelvin's isotropic helicoid
Darci Collins, Rami J. Hamati, Fabien Candelier +3
Nearly 150 years ago, Lord Kelvin proposed the isotropic helicoid, a particle with isotropic yet chiral interactions with a fluid, so that translation couples to rotation. An imple…
Time-dependent lift and drag on a rigid body in a viscous steady linear flow
Fabien Candelier, Bernhard Mehlig, Jacques Magnaudet
We compute the leading-order inertial corrections to the instantaneous force acting on a rigid body moving with a time-dependent slip velocity in a linear flow field, assuming that…
Inertial drag on a sphere settling in a stratified fluid
R. Mehaddi, F. Candelier, B. Mehlig
We compute the drag force on a sphere settling slowly in a quiescent, linearly stratified fluid. Stratification can significantly enhance the drag experienced by the settling parti…
Settling of an asymmetric dumbbell in a quiescent fluid
F. Candelier, B. Mehlig
We compute the hydrodynamic torque on a dumbbell (two spheres linked by a massless rigid rod) settling in a quiescent fluid at small but finite Reynolds number. The spheres have th…
The role of inertia for the rotation of a nearly spherical particle in a general linear flow
F. Candelier, J. Einarsson, F. Lundell +2
We analyse the angular dynamics of a neutrally buoyant nearly spherical particle immersed in a steady general linear flow. The hydrodynamic torque acting on the particle is obtaine…
Effect of weak fluid inertia upon Jeffery orbits
J. Einarsson, F. Candelier, F. Lundell +2
We consider the rotation of small neutrally buoyant axisymmetric particles in a viscous steady shear flow. When inertial effects are negligible the problem exhibits infinitely many…
Rotation of a spheroid in a simple shear at small Reynolds number
J. Einarsson, F. Candelier, F. Lundell +2
We derive an effective equation of motion for the orientational dynamics of a neutrally buoyant spheroid suspended in a simple shear flow, valid for arbitrary particle aspect ratio…
Note on the method of matched-asymptotic expansions for determining the force acting on a particle
Fabien Candelier, Rabah Mehaddi, Olivier Vauquelin
This paper is an addendum to the article by Candelier, Mehaddi & Vauquelin (2013) where the motion of a particle in a stratified fluid is investigated theoretically, at small Reyno…
The history force on a small particle in a linearly stratified fluid
Fabien Candelier, Rabah Mehaddi, Olivier Vauquelin
The hydrodynamic force experienced by a small spherical particle undergoing an arbitrary time-dependent motion in a density-stratified fluid is investigated theoretically. The stud…
