Viscoelastic wetting transition: beyond lubrication theory
Minkush Kansal, Charu Datt, Vincent Bertin +1
The dip-coating geometry, where a solid plate is withdrawn from or plunged into a liquid pool, offers a prototypical example of wetting flows involving contact-line motion. Such fl…
Viscoelastic wetting: Cox-Voinov theory with normal stress effects
Minkush Kansal, Vincent Bertin, Charu Datt +2
The classical Cox-Voinov theory of contact line motion provides a relation between the macroscopically observable contact angle, and the microscopic wetting angle as a function of…
A thin-film equation for a viscoelastic fluid, and its application to the Landau-Levich problem
Charu Datt, Minkush Kansal, Jacco H. Snoeijer
Thin-film flows of viscoelastic fluids are encountered in various industrial and biological settings. The understanding of thin viscous film flows in Newtonian fluids is very well…
Elastic Rayleigh-Plateau instability: Dynamical selection of nonlinear states
Anupam Pandey, Minkush Kansal, Miguel A. Herrada +2
A slender thread of elastic hydrogel is susceptible to a surface instability that is reminiscent of the classical Rayleigh-Plateau instability of liquid jets. The final, highly non…
