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…
Breakup of viscous liquid bridges on solid surfaces
Salar Farokhi, Peyman Rostami, Günter K. Auernhammer +1
The breakup dynamics of viscous liquid bridges on solid surfaces is studied experimentally. It is found that the dynamics bears similarities to the breakup of free liquid bridges i…
Spreading of a viscoelastic drop on a solid substrate
Peyman Rostami, Mathis Fricke, Simon Schubotz +3
We study the spreading of viscous and viscoelastic drops on solid substrates with different wettability. In the early stages of spreading, we find that the viscoelastic drop spread…
Capillary filling in drop merging: dynamics of the four-phase contact point
Peyman Rostami, Günter K. Auernhammer
The merging of immiscible drops differs significantly from the merging of miscible drops due to the formation of a liquid-liquid interface between drops. The immiscibility requires…
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…
