Data-Driven Surrogate Modeling for Micromixing of Non-Newtonian Fluids in Sinusoidal Converging-Diverging Microchannels
Kritagya Sharma, Bimalendu Mahapatra
Micromixing of non-Newtonian fluids remains challenging because laminar flow at microscales restricts transverse transport primarily to molecular diffusion. In this study, we inves…
Viscoelastic flow of an Oldroyd-B fluid through a slowly varying contraction-expansion channel: pressure drop and elastic stress relaxation
Yali Kedem, Bimalendu Mahapatra, Evgeniy Boyko
Viscoelastic fluid flows in narrow non-uniform geometries are ubiquitous in various engineering applications and physiological flow systems. For such flows, one of the key interest…
Elasto-viscous regime in coalescence of viscoelastic droplets
Pallavi Katre, Bimalendu Mahapatra, Manaswita Karmakar +3
We report a regime transition in the coalescence of concentrated polymeric droplets in a pendant-pendant configuration. While Newtonian droplet coalescence has been extensively stu…
Viscoelastic fluid flow in a slowly varying planar contraction: the role of finite extensibility on the pressure drop
Bimalendu Mahapatra, Tachin Ruangkriengsin, Howard A. Stone +1
We analyze the steady viscoelastic fluid flow in slowly varying contracting channels of arbitrary shape and present a theory based on the lubrication approximation for calculating…
Alterations in electroosmotic slip velocity: combined effect of viscoelasticity and surface potential undulation
Bimalendu Mahapatra, Aditya Bandopadhyay
In computational models of microchannel flows, the Helmholtz-Smoluchowski slip velocity boundary condition is often used because it approximates the motion of the electric double l…
Experimental investigations on geometry modulated solute mixing in viscoelastic media
Bimalendu Mahapatra, Aditya Bandopadhyay
In this study, geometrically modified microchannels fabricated using stereolithography technique are employed to analyze micromixing of polymeric solutions. Experimental and numeri…
Low Reynolds number pulsatile flow of a viscoelastic fluid through a channel: Effects of fluid rheology and pulsation parameters
Subhasisa Rath, Bimalendu Mahapatra
As the first endeavour, we have analyzed the pulsatile flow of Oldroyd-B viscoelastic fluid where the combined effects of fluid elasticity and pulsation parameters on the flow char…
