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…
A finite-element model for computing fluid flow inside a sessile evaporating droplet on a solid surface
Manish Kumar, Rajneesh Bhardwaj
A finite element model was developed to compute the fluid flow inside a sessile evaporating droplet on hydrophilic substrate in ambient conditions. The evaporation is assumed as qu…
Evaporation of initially heated sessile droplets and the resultant dried colloidal deposits on substrates held at ambient temperature
Sanghamitro Chatterjee, Manish Kumar, Janani S Murallidharan +1
The present study experimentally and numerically investigates the evaporation and resultant patterns of dried deposits of aqueous colloidal sessile droplets, when the droplets are…
A Combined Computational and Experimental Investigation on Evaporation of a Sessile Water Droplet on a Heated Hydrophilic Substrate
Manish Kumar, Rajneesh Bhardwaj
We numerically and experimentally investigate evaporation of a sessile droplet on a heated substrate. We develop a finite element (FE) model in two-dimensional axisymmetric coordin…
