Modelling of the dewetting of ultra-thin liquid films on chemically patterned substrates: linear spectrum and deposition patterns
Tilman Richter, Paolo Malgaretti, Jens Harting
Liquid films of nanometric thickness are prone to spinodal dewetting driven by disjoining pressure, meaning that a non-wetting liquid film of homogeneous thickness in the range of…

Modeling of thin liquid films with arbitrary many layers
Tilman Richter, Paolo Malgaretti, Jens Harting
We propose the generalization of the thin film equation (TFE) to arbitrarily many immiscible liquid layers. Then, we provide different pathways for deriving the hydrodynamic pressu…

To coalesce or not to coalesce: Droplets and surface tension gradients
Stefan Zitz, Tilman Richter, Konstantinos Missios +1
We numerically study the coalescence dynamics of two sessile droplets with radii . The droplets are placed on top of a rigid substrate with a contact angle of .…
