Microfluidic extensional rheometry using a hyperbolic contraction geometry
Microfluidic devices are ideally suited for the study of complex fluids undergoing large deformation rates in the absence of inertial complications. In particular, a microfluidic contraction geometry can be utilized to characterize the material response of complex fluids in an extensionally-dominated flow, but the mixed nature of the flow kinematics makes quantitative measurements of material f...
متن کاملCapillary breakup extensional rheometry of a wormlike micellar solution
The behaviour of a cetylpyridinium chloride/sodium salicylate wormlike micellar system undergoing capillary breakup is investigated experimentally. The transient elongational flow induced in a thinning thread is used to study the apparent viscosity and effective relaxation time of the micellar network in extension. The sensitivity of the material response to initial conditions and deformation h...
متن کامل‘Beads on a String’ Structures and Extensional Rheometry using Jet Break-up
1. Introduction: Surface tension driven break-up of cylindrical fluid elements into droplets plays a crucial role in the use or processing of many multicomponent complex fluids like paints, inks, insecticides, cosmetics, food, etc [1, 2]. These industrial fluids are typically formulated using dilute polymer solutions, and are exposed to a wide range of shear and extension rates. Since the polym...
متن کاملFilament stretching and capillary breakup extensional rheometry measurements of viscoelastic wormlike micelle solutions
filament stretching extensional rheometer and capillary breakup extensional rheometer are used o measure the extensional rheology of a series of wormlike micelle solutions experiencing a niaxial elongational flow. The experiments are performed using a series of wormlike micelle olutions of both cetylpyridinium chloride and sodium salicylate NaSal in an aqueous sodium hloride solution and cetylt...
متن کاملHow to Characterize Yield Stress Fluids with Capillary Breakup Extensional Rheometry (CaBER)?
© Appl. Rheol. 19 (2009) 41969 Abstract: Filament breakup of high viscosity fluids with apparent yield stress has been investigated and strategies for an appropriate characterization of their behavior in CaBER experiments are discussed. Filament profiles of such fluids exhibit significant concave curvature. Accurate determination of filament shape is mandatory for understanding deformation beha...
