Unveiling the stress field in a flowing complex fluid with velocity and microstructure imaging
Ashinth Mangesh, Manish Kumar, Matthew E. Helgeson +1
The stress in a flowing complex fluid such as a solution of polymers, surfactants and/or colloidal particles is a fundamental dynamic property of the material. It reflects the evol…
Microcirculatory blood flow with aberrant levels of red blood cell aggregation
Xiaopo Cheng, Dell Zimmerman, Elizabeth Iffrig +2
Recent clinical results indicate that aberrant erythrocyte aggregation in hematological disorders is accompanied by endothelial damage and glycocalyx disruption, but the underlying…
Nested traveling wave structures in elastoinertial turbulence
Manish Kumar, Michael D. Graham
Elastoinertial turbulence (EIT) is a chaotic flow resulting from the interplay between inertia and viscoelasticity in wall bounded shear flows. Understanding EIT is important becau…
Free-space and near-wall dynamics of a flexible sheet sedimenting in Stokes flow
Yijiang Yu, Michael Graham
We present a numerical study of a thin elastic sheet with small extensibility freely sedimenting in a viscous fluid. Two scenarios are investigated: sedimentation in free space and…
