Exploratory Study of Chaotic Behavior in Walking Droplets
Emily Dunn, Bavand Keshavarz, Earl Dowell
The interaction of 'walking droplets' and capillary waves in a weakly subcritical Faraday wave experiment has been studied as a hydrodynamic analog to Bohmian quantum mechanics (se…
The hidden hierarchical nature of soft particulate gels
Minaspi Bantawa, Bavand Keshavarz, Michela Geri +4
Soft particulate gels include materials we can eat, squeeze, or 3D print. From foods to bio-inks to cement hydrates, these gels are composed of a small amount of particulate matter…
Computing the linear viscoelastic properties of soft gels using an Optimally Windowed Chirp protocol
Mehdi Bouzid, Bavand Keshavarz, Michela Geri +3
We use molecular dynamics simulations of a model three-dimensional particulate gel, to investigate the linear viscoelastic response. The numerical simulations are combined with a n…
Time-Resolved Mechanical Spectroscopy of Soft Materials via Optimally Windowed Chirps
Michela Geri, Bavand Keshavarz, Thibaut Divoux +3
The ability to measure the bulk dynamic behavior of soft materials with combined time- and frequency-resolution is instrumental for improving our fundamental understanding of conne…
Nonlinear viscoelasticity and generalized failure criterion for polymer gels
Bavand Keshavarz, Thibaut Divoux, Sébastien Manneville +1
Polymer gels behave as soft viscoelastic solids and exhibit a generic nonlinear mechanical response characterized by pronounced stiffening prior to irreversible failure, most often…
When Viscous Jets Collide; Liquid Chains, Threads, Webs, Fishbones and Balloons
Bavand Keshavarz, Gareth H. McKinley
In this fluid dynamics video prepared for the APS-DFD Gallery of Fluid Motion we study the collision of two identical viscous jets at different jet speeds and collision eccentricit…
Kelvin-Helmholtz and Buckling Instabilities for a Viscoelastic Liquid
Bavand Keshavarz, Gareth McKinley
In this fluid dynamics video prepared for the APS-DFD Gallery of Fluid Motion we study the Kelvin-Helmholtz instability for both Newtonian and viscoelastic jets. The nonlinear dyna…
