[Soft-matter] Soft Matter & Complex Systems Seminar on 7 Mar 2025

[Maciej Lisicki]

Dear Soft Matter & Complex Systems Colleagues and Friends,

On Friday 7 March 2025 at 9:30 AM at the UW Faculty of Physics (Pasteura 5, Warsaw; room 1.40) we are hosting a seminar during which 

King Ng (Institute of Physics, Polish Academy of Sciences)

will give a talk
Liquid droplet oscillations on a vibrating substrate

Abstract

We study the oscillations of liquid droplets on substrates in macroscopic scale using Many-body Dissipative Particle Dynamics (MDPD). In this study, we focus on the harmonic droplet oscillations which are induced by sinusoidal forcing from horizonal substrate vibrations in one-dimension. Our investigation examines the topological changes of the droplet in various sizes and oscillation modes, considering different vibration frequencies and amplitudes. We also explore the role of the droplet's natural oscillation mode. Additionally, we demonstrate the effect of surface wettability on droplet oscillations, ranging from hydrophilic to hydrophobic surfaces, by parametrically tuning the equilibrium contact angles. Our MDPD simulations are compared with experimental results. This approach aims to optimize systems involving droplet movement driven by vibrating substrates.

We warmly welcome everyone to attend the talk and the Soft Matter Coffee Break after the seminar, held in room 2.63 (2nd floor).
