The effect of inertia on the orientation dynamics of anisotropic particles in simple shear flow

Dabade, Vivekanand; Marath, Navaneeth K.; Subramanian, Ganesh (Cambridge University Press, 2016)

It is well known that, under inertialess conditions, the orientation vector of a torque-free neutrally buoyant spheroid in an ambient simple shear flow rotates along so-called Jeffery orbits, a one-parameter family of ...
Effects of inertia and viscoelasticity on sedimenting anisotropic particles

Dabade, Vivekanand; Marath, Navaneeth K.; Subramanian, Ganesh (Cambridge University Press, 2015)

An axisymmetric particle sedimenting in an otherwise quiescent Newtonian fluid, in the Stokes regime, retains its initial orientation. For the special case of a spheroidal geometry, we examine analytically the effects of ...
Stochastic dynamics of active swimmers in linear flows

Sandoval, Mario; Marath, Navaneeth K.; Subramanian, Ganesh; Lauga, Eric (Cambridge Univ Press, 2014)

Most classical work on the hydrodynamics of low-Reynolds-number swimming addresses deterministic locomotion in quiescent environments. Thermal fluctuations in fluids are known to lead to a Brownian loss of the swimming ...
