The stability of viscoelastic fluids in complex flows : the role of shear and extensional rheology
Understanding the flow of polymeric fluids is important for optimizing commercial processes such as injection molding and fiber spinning. The combination of streamwise curvature and elastic normal stresses can lead to the onset of elastic flow instabilities, severely rate-limiting such processes. …

Propulsion By Sinusoidal Locomotion: A Motion Inspired By Caenorhabditis Elegans
… records of C. elegans' movement in different fluids, including Newtonian and non-Newtonian fluids. The experimental and numerical studies of swimming C. elegans has revealed three conclusions. First, though the amplitude and wavelength are varying with time, the motion of swimming C. elegans …

Modeling the Motion of Solid Objects Immersed in Viscoelastic Fluids
Flows of viscoelastic fluids around immersed objects have long been a subject of interest in both experimental and theoretical studies. Such flows are used as benchmarking problems for validation of advanced numerical methods and the predictions of equations of state, as model systems for larger …

Viscous Fingering Instability of Complex Fluids in a Radial Hele-Shaw Cell
… can develop at the interface between the two fluids. The instability manifests itself in the form of finger-like patterns of the displacing fluid propagating through the displaced one. In this work, viscous fingering instabilities involving complex fluids in a radial Hele-Shaw is investigated. …
