Weber-number scaling and the distance dependence of drop size in full-cone pressure-swirl sprays
Bilal Ben Jemaa, Vincent He, Marko Trifunović +2
A pressure-swirl nozzle converts the feed pressure into a swirling conical sheet that breaks into ligaments and then into drops. The size of the drops governs the deposition and dr…
The role of the second normal stress difference in rod-climbing effect
Rishabh More
The Weissenberg (rod-climbing) effect, i.e., the rise of a viscoelastic fluid along a thin rotating rod, has long served as a canonical demonstration of elasticity and normal-stres…
Elasto-Inertial Instability in Torsional Flows of Shear-Thinning Viscoelastic Fluids
Rishabh V. More, Eugene Pashkovski, Reid Patterson +1
It is well known that inertia-free shearing flows of a viscoelastic fluid with curved streamlines, such as the torsional flow between a rotating cone and plate, or the flow in a Ta…
Rod-climbing rheometry revisited
Rishabh V. More, Reid Patterson, Eugene Pashkovski +1
The rod-climbing or Weissenberg effect in which the free surface of a complex fluid climbs a thin rotating rod is a popular and convincing experiment demonstrating the existence of…
Rheology of dense fiber suspensions: Origin of yield stress, shear thinning and normal stress differences
Monsurul Khan, Rishabh V. More, Luca Brandt +1
We explain the origins of yield stress, shear-thinning, and normal stress differences in rigid fiber suspensions. We investigate the interplay between the hydrodynamic, colloidal a…
A constitutive model for viscosity of dense fiber suspension
Monsurul Khan, Rishabh V. More, Arezoo M. Ardekani
We propose a constitutive model to predict the viscosity of fiber suspensions, which undergoes shear thinning, at various volume fractions, aspect ratios, and shear stresses/rates.…
Rheology of concentrated suspension of fibers with load dependent friction coefficient
Monsurul Khan, Rishabh V. More, Arash Alizad Banaei +2
We numerically investigate the effects of fiber aspect ratio, roughness, flexibility, and flow inertia on the rheology of concentrated suspensions. We perform direct numerical simu…
Orientation instability of settling spheroids in a linearly density stratified fluid
Rishabh V. More, Mehdi N. Ardekani, Luca Brandt +1
Much work has been done to understand the settling dynamics of spherical particles in a homogeneous and a stratified fluid. However, the effects of shape anisotropy on the settling…
