Stagnation points at grain contacts generate an elastic flow instability in 3D porous media
Emily Y. Chen, Christopher A. Browne, Simon J. Haward +2
Many environmental, energy, and industrial processes involve the flow of polymer solutions in three-dimensional (3D) porous media where fluid is confined to navigate through comple…
The interplay of plasticity and elasticity in elastoviscoplastic flows in wavy channels
Mohamed S. Abdelgawad, Simon J. Haward, Amy Q. Shen +1
Elastoviscoplastic (EVP) fluids, which exhibit both solid-like and liquid-like behavior depending on the applied stress, are critical in industrial processes involving complex geom…
Effects of polydispersity and concentration on elastocapillary thinning of dilute polymer solutions
Vincenzo Calabrese, Amy Q. Shen, Simon J. Haward
The thinning of liquid bridges under capillary stress occurs in widespread processes like jetting, dripping, and spraying, and creates a strong extensional flow capable of stretchi…
From yield stress to elastic instabilities: Tuning the extensional behavior of elastoviscoplastic fluid
Mohamed S. Abdelgawad, Simon J. Haward, Amy Q. Shen +1
In this study, we delve into the intricacies of elastoviscoplastic (EVP) fluids, particularly focusing on how polymer additives influence their extensional behavior. Our findings r…
How do polymers stretch in capillary-driven extensional flows?
Vincenzo Calabrese, Amy Q. Shen, Simon J. Haward
Measurements of the capillary-driven thinning and breakup of fluid filaments are widely used to extract extensional rheological properties of complex materials. For viscoelastic (e…
