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…
Stagnation points control chaotic fluctuations in viscoelastic porous media flow
Simon J. Haward, Cameron C. Hopkins, Amy Q. Shen
Viscoelastic flows through porous media become unstable and chaotic beyond critical flow conditions, impacting industrial and biological processes. Recently, Walkama \textit{et al.…
Microtomographic PIV measurements of viscoelastic instabilities in a 3D micro-contraction
Daniel W. Carlson, Amy Q. Shen, Simon J. Haward
Viscoelastic flow through an abrupt planar contraction geometry above a certain Weissenberg number (Wi) is well known to become unstable upstream of the contraction plane via a cen…
Population genetics in microchannels
Anzhelika Koldaeva, Hsieh-Fu Tsai, Amy Q. Shen +1
Spatial constraints such as rigid barriers affect the dynamics of cell populations, potentially altering the course of natural evolution. In this paper, we investigate the populati…
