Effect of polymer additives on dynamics of water level in an open channel
Manish Kumar, Michael D. Graham
The presence of a tiny amount of polymers (a few parts per million) in a fluid dramatically reduces turbulent drag. For this reason, polymer additives have been proposed to be used…

Stress and stretching regulate dispersion in viscoelastic porous media flows
Manish Kumar, Derek M. Walkama, Arezoo M. Ardekani +1
In this work, we study the role of viscoelastic instability in the mechanical dispersion of fluid flow through porous media at high Peclet numbers. Using microfluidic experiments a…
