Extensional rheometry of mobile fluids. Part II: Comparison between the uniaxial, planar and biaxial extensional rheology of dilute polymer solutions using numerically-optimized stagnation point microfluidic devices
Simon J. Haward, Stylianos Varchanis, Gareth H. McKinley +2
In Part I of this paper [Haward et al. submitted (2023)], we presented a new three-dimensional microfluidic device (the optimized uniaxial and biaxial extensional rheometer, OUBER)…
Extensional rheometry of mobile fluids. Part I: OUBER, an optimized uniaxial and biaxial extensional rheometer
Simon J. Haward, Francisco Pimenta, Stylianos Varchanis +4
We present a numerical optimization of a "6-arm cross-slot" device, yielding several three-dimensional shapes of fluidic channels designed to impose close approximations to ideal u…
Canopy elastic turbulence: spontaneous formation of waves in beds of slender microposts
Charlotte de Blois, Simon J. Haward, Amy Q. Shen
In a viscoelastic flow over a microfluidic canopy of polymeric pillars, we report the spontaneous emergence of waves in the form of propagating regions of low flow velocity compare…
Alignment of colloidal rods in crowded environments
Vincenzo Calabrese, Stylianos Varchanis, Simon J. Haward +1
Understanding the hydrodynamic alignment of colloidal rods in polymer solutions is pivotal for manufacturing structurally ordered materials. How polymer crowding influences the flo…
A fast and efficient tool to study the rheology of dense suspensions
Alessandro Monti, Vikram Rathee, Amy Q. Shen +1
A cutting-edge software is presented to tackle the Newton-Euler equations governing the dynamics of granular flows and dense suspensions in Newtonian fluids. In particular, we prop…
Perspectives on viscoelastic flow instabilities and elastic turbulence
Sujit S. Datta, Arezoo M. Ardekani, Paulo E. Arratia +20
Viscoelastic fluids are a common subclass of rheologically complex materials that are encountered in diverse fields from biology to polymer processing. Often the flows of viscoelas…
