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…
CFD analysis of electroviscous effects in electrolyte liquid flow through heterogeneously charged non-uniform microfluidic device
Jitendra Dhakar, Ram Prakash Bharti
In this work, the pressure-driven flow of symmetric electrolyte liquid through a heterogeneously charged contraction-expansion (4:1:4) microfluidic device has been investigated num…
CFD analysis of the influence of contraction size on electroviscous flow through the slit-type non-uniform microfluidic device
Jitendra Dhakar, Ram Prakash Bharti
The electroviscous effects are relevant in controlling and manipulating the fluid, thermal, and mass transport microfluidic processes. The existing research has mainly focused on t…
CFD analysis of electroviscous effects in electrolyte liquid flow through heterogeneously charged uniform microfluidic device
Jitendra Dhakar, Ram Prakash Bharti
This study has numerically investigated the charge-heterogeneity effects in the electroviscous flow of symmetric (:) electrolyte liquid through a uniform slit microfluidic de…
