Colloid recovery from porous structures under ambient flow: enhanced extraction via phoretic and osmotic mechanisms
Jitendra Dhakar, Kapil Upadhyaya, Akash Choudhary
Chemical gradients are widely employed to enhance particle transport in porous media, such as laundry detergency and enhanced oil recovery. Diffusiophoresis and diffusioosmosis ref…
Tuning Cross-stream Lift in Viscoelastic Shear: Distinct Hydrodynamic Signatures of Force-bearing and Force-free Mechanisms
Soumyodeep Chowdhury, Kushagra Tiwari, Jitendra Dhakar +1
We investigate the lift and drag corrections acting on a particle suspended in a planar viscoelastic shear flow when the particle is tuned to translate relative to the flow by an e…
Electroviscous effects in electrolyte liquid flow through an oppositely-charged contraction-expansion microfluidic slit device
Jitendra Dhakar, Ram Prakash Bharti
Electrokinetic flows in microchannels with opposite charge asymmetry, i.e., unequal and contrasting surface charges on opposing channel walls, significantly influence microfluidic…
On the influence of electrolytic gradient orientation on phoretic transport in dead-end pores
Kushagra Tiwari, Jitendra Dhakar, Kapil Upadhyaya +1
Electrolytic diffusiophoresis refers to directional migration of colloids due to interfacial forces that develop in response to local electrolytic concentration () gradients. Th…
