Rheology modulated non-equilibrium fluctuations in time-dependent diffusion processes
Debonil Maity, Aditya Bandopadhyay, Suman Chakraborty
The effect of non-Newtonian rheology, manifested through a viscoelastic linearized Maxwell model, on the time-dependent non-equilibrium concentration fluctuations due to free diffu…
Effect of Ionic Advection on Electroosmosis over Charge Modulated Surfaces: Beyond the Weak Field Limit
Uddipta Ghosh, Suman Chakraborty
The present study deals with the effect of ionic advection on electroosmotic flow over charge modulated surfaces in a generalized paradigm when the classically restrictive "weak fi…
Shape Evolution of Sandwitched Droplet in Microconfined Shear Flow
Kaustav Chaudhury, Debabrata DasGupta, Tamal Roy +1
Droplets confined in a microfluidic channel often exhibit intriguing shapes, primarily attributable to complex hydrodynamic interactions over small scales. We show that effect of v…
Droplet migration characteristics in confined oscillatory microflows
Kaustav Chaudhury, Shubhadeep Mandal, Suman Chakraborty
We analyze the migration characteristics of a droplet in an oscillatory flow field in a parallel plate micro-confinement. Using phase filed formalism, we capture the dynamical evol…
Characteristics of dynamic contact-angle in presence of surface-charge
Palash V. Acharya, Kaustav Chaudhury, Suman Chakraborty
We account for the presence of surface charges towards describing variations in the dynamic contact angle of an advancing liquid-gas meniscus. Starting from the thin-film based for…
Wettability Modulated Charge Inversion and Ionic Transport in Nanofuidic Channels
Vaseem Akram Shaik, Aditya Bandopadhyay, Syed Sahil Hossain +1
We unveil the role of substrate wettability on the reversal in the sign of the interfacial charge distribution in a nanochannel in presence of multivalent ions. In sharp contrast t…
Electrohydrodynamic migration of a spherical drop in a general quadratic flow
Shubhadeep Mandal, Aditya Bandopadhyay, Suman Chakraborty
We investigate the motion of a spherical drop in a general quadratic flow acted upon by an arbitrarily oriented externally applied uniform electric field. The drop and media are co…
Uniform electric field induced lateral migration of a sedimenting drop
Aditya Bandopadhyay, Shubhadeep Mandal, Suman Chakraborty
We investigate the motion of a sedimenting spherical drop in the presence of an applied uniform electric field in an otherwise arbitrary direction in the limit of low surface charg…
The effect of interfacial slip on the motion and deformation of a droplet in an unbounded arbitrary Stokes flow
Shubhadeep Mandal, Aditya Bandopadhyay, Suman Chakraborty
The motion and deformation of a droplet suspended in an unbounded fluid with an arbitrary, but Stokesian, imposed flow is investigated when there is a slip at the interface between…
