Rheological Insights from the Oscillation Dynamics of Viscoelastic Sessile Drops
Peyman Rostami, Alfonso A. Castrejón-Pita, Günter K. Auernhammer
This study investigates the oscillation behavior of a sessile drop placed on a hydrophobic substrate subjected to vertical vibrations with varying frequencies and amplitudes. We ex…
Dynamic Wetting by Concentrated Granular Suspensions
Reza Azizmalayeri, Peyman Rostami, Thomas Witzmann +2
Many functional materials, such as paints and inks used in applications like coating and 3D printing, are concentrated granular suspensions. In such systems, the contact line dynam…
Coalescence of viscoelastic drops on a solid substrate
Peyman Rostami, Alexander Erb, Reza Azizmalayeri +3
This study investigated the coalescence of polymer solution drops on the solid substrates. When two drops meet at their contact line on a substrate, the liquid bridge connecting th…
Flow profiles near receding three--phase contact lines: Influence of surfactants
Benedikt B. Straub, Henrik Schmidt, Peyman Rostami +5
The dynamics of wetting and dewetting is largely determined by the velocity field near the contact lines. For water drops it has been observed that adding surfactant decreases the…
