Stood-up drop to measure receding contact angles
Diego Díaz, Aman Bhargava, Franziska Walz +9
The wetting behavior of drops on natural and industrial surfaces is determined by the advancing and receding contact angles. They are commonly measured by the sessile drop techniqu…
Holes in Sheets: Double-Threshold Rupture of Draining Liquid Films
Ayush K. Dixit, Chunheng Zhao, Stéphane Zaleski +2
Classical rupture is attributed to molecular (van der Waals) forces acting at nanometric thicknesses. Nonetheless, micron-thick liquid sheets routinely perforate far above the scal…
Implementation of integral surface tension formulations in a volume of fluid framework and their applications to Marangoni flows
Mandeep Saini, Vatsal Sanjay, Youssef Saade +2
Accurate numerical modeling of surface tension has been a challenging aspect of multiphase flow simulations. The integral formulation for modeling surface tension forces is known t…
Unifying theory of scaling in drop impact: Forces & maximum spreading diameter
Vatsal Sanjay, Detlef Lohse
The dynamics of drop impact on a rigid surface -- omnipresent in nature and technology -- strongly depends on the droplet's velocity, its size, and its material properties. The mai…
Viscoelastic Worthington jets & droplets produced by bursting bubbles
Ayush K. Dixit, Alexandros Oratis, Konstantinos Zinelis +2
Bubble bursting and subsequent collapse of the open cavity at free surfaces of contaminated liquids can generate aerosol droplets, facilitating pathogen transport. After film ruptu…
Deforming ice with drops
Duco van Buuren, Pallav Kant, Jochem G. Meijer +2
A uniform solidification front undergoes non-trivial deformations when encountering an insoluble dispersed particle in a melt. For solid particles, the overall deformation characte…
Enhanced bubble growth near an advancing solidification front
Jochem G. Meijer, Duarte Rocha, Annemarie M. Linnenbank +2
Frozen water might appear opaque since gas bubbles can get trapped in the ice during the freezing process. They nucleate and then grow near the advancing solidification front, due…
The role of viscosity on drop impact forces on non-wetting surfaces
Vatsal Sanjay, Bin Zhang, Cunjing Lv +1
A liquid drop impacting a rigid substrate undergoes deformation and spreading due to normal reaction forces, which are counteracted by surface tension. On a non-wetting substrate,…
