Streak generation in viscosity-stratified wall-bounded flows
Anagha Madhusudanan, Simon J. Illingworth, Rama Govindarajan
Streamwise elongated flow structures, or streaks, dominate wall-bounded flows. We show that the renowned lift-up mechanism, that generates streaks, is significantly altered by visc…
Sedimentation and shear-induced dynamics of spheroids in fluids with spatial viscosity variations
Arjun Sharma, Peter A. Bosler, Rama Govindarajan +1
A generalized reciprocal theorem is used to relate the force and torque induced on a particle in an inertia-less fluid with small variation in viscosity to integrals involving Stok…
Emergence of capillary waves in miscible co-flowing fluids
Alessandro Carbonaro, Giovanni Savorana, Luca Cipelletti +2
We show that capillary waves can exist at the the boundary between miscible co-flowing fluids. We unveil that the interplay between transient interfacial stresses and confinement d…
Mechanism of instability in non-uniform dusty channel flow
Anup Kumar, Rama Govindarajan
Particles in pressure-driven channel flow are often inhomogeneously distributed. Two modes of low-Reynolds number instability, absent in Poiseuille flow of clean fluid, are created…
