Charged Obstacles Augment Electrokinetic Energy Conversion Efficiency
Tanoy Kahali, Antarip Poddar, Jayabrata Dhar +1
In the present study, we delineate the effect of introducing flow obstructions on streaming potential and energy conversion efficiency in a narrow fluidic confinement taking into c…
Thermally modulated cross-stream migration of a surfactant-laden deformable drop in a Poiseuille flow
Sayan Das, Suman Chakraborty
In the present study, we investigate the cross-stream migration of a deformable droplet suspended in a non-isothermal Poiseuille flow in the presence of bulk-insoluble surfactants.…
Complex Fluid-Fluid Interface may Non Trivially Dictate Droplet Deformation in an Incipient Flow
Sayan Das, Shubhadeep Mandal, Suman Chakraborty
The present study theoretically predicts the effect of interfacial viscosity on the deformation of a compound drop as well as on the bulk rheology. The system at hand comprises of…
Thermophoretically driven capillary transport of nanofluid in a microchannel
Soumya Bandyopadhyay, Suman Chakraborty
We investigate the interplay of thermophoretic force and interfacial tension on the capillary filling dynamics of a Newtonian nanofluid in a microchannel. In our model, we also con…
Effect of Marangoni stress on the bulk rheology of a dilute emulsion of surfactant-laden deformable droplets in linear flows
Shubhadeep Mandal, Sayan Das, Suman Chakraborty
In the present study we analytically investigate the deformation and bulk rheology of a dilute emulsion of surfactant-laden droplets suspended in a linear flow. We use an asymptoti…
Cross-stream migration characteristics of a deformable droplet in a non-isothermal Poiseuille Flow through Microfluidic Channel
Sayan Das, Shubhadeep Mandal, Suman Chakraborty
The migration characteristics of a suspended deformable droplet in a parallel plate microchannel is studied, both analytically and numerically, under the combined influence of a co…
Cross-stream migration of a surfactant-laden deformable droplet in a Poiseuille flow
Sayan Das, Shubhadeep Mandal, Suman Chakraborty
The motion of a viscous deformable droplet suspended in an unbounded Poiseuille flow in the presence of bulk-insoluble surfactants is studied analytically. Assuming the convective…
Liquid crystal induced elasto-capillary suppression of crack formation in thin colloidal films
Udita Uday Ghosh, Jayabrata Dhar, Suman Chakraborty +1
Drying of colloidal droplets on solid, rigid substrates is associated with a capillary pressure developing within the droplet. In due course of time, the capillary pressure builds…
Transient Electroosmosis of a Maxwell fluid in a Rotating Microchannel
P Kaushik, Shubhadeep Mandal, Suman Chakraborty
The transient electroosmotic flow of Maxwell fluid in a rotating microchannel is investigated both analytically and numerically. We bring out the complex dynamics of the flow durin…
Thermocapillary effect on the cross-stream migration of a surfactant-laden droplet in Poiseuille flow
Sayan Das, Shubhadeep Mandal, S. K. Som +1
The motion of a viscous droplet in unbounded Poiseuille flow under the combined influence of bulk-insoluble surfactant and linearly varying temperature field aligned in the directi…
