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…
Thixotropy versus viscoelasticity: a matter of time
Rishabh V. More
Thixotropic and viscoelastic materials both retain their deformation history and are difficult to distinguish. However, a stationary linear response obeys the Kramers-Kronig relati…
Strain-transport superposition in shear-thinning dense non-Brownian suspensions
Rishabh V. More
Shear thinning in dense non-Brownian suspensions is often attributed to shear-induced microstructural evolution, including changes in alignment, anisotropy, and near-contact statis…
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…
To roll or not to roll(?) is the yield stress (in soft particulate gels)
Rishabh More, Gareth Mckinley
While it is widely acknowledged that system-spanning particulate structures contribute to the observed yield stress and shear-thinning in attractive colloidal gels, a comprehensive…
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…
A unifying mechanism to explain the rate dependent rheological behavior in non-Brownian suspensions: One curve to unify them all
Rishabh V. More, Arezoo M. Ardekani
We propose a unifying mechanism based on the Stribeck curve for the coefficient of friction between the particles to capture the shear thinning - Newtonian plateau - shear thickeni…
