Surface tension and wetting at free surfaces in Smoothed Particle Hydrodynamics
Michael Blank, Prapanch Nair, Thorsten Pöschel
Surface tension and wetting are dominating physical effects in micro and nanoscale flows. We present an efficient and reliable model of surface tension and equilibrium contact angl…
SPIRAL: An Efficient Algorithm for the Integration of the Equation of Rotational Motion
Carlos Andrés del Valle, Vasileios Angelidakis, Sudeshna Roy +2
We introduce Spiral, a third-order integration algorithm for the rotational motion of extended bodies. It requires only one force calculation per time step, does not require quater…
Shear zones in granular mixtures of hard and soft particles with high and low friction
Aditya Pratap Singh, Vasileios Angelidakis, Thorsten Pöschel +1
Granular materials show inhomogeneous flows characterized by strain localization. When strain is localized in a sheared granular material, rigid regions of a nearly undeformed stat…
Structural fluctuations in thin cohesive particle layers in powder-based additive manufacturing
Sudeshna Roy, Hongyi Xiao, Vasileios Angelidakis +1
Producing dense and homogeneous powder layers with smooth free surface is challenging in additive manufacturing, as interparticle cohesion can strongly affect the powder packing st…
Approximate Expressions for the Capillary Force and the Surface Area of a Liquid Bridge between Identical Spheres
Meysam Bagheri, Sudeshna Roy, Thorsten Pöschel
We consider a liquid bridge between two identical spheres and provide approximate expressions for the capillary force and the exposed surface area of the liquid bridge as functions…
Structural features of jammed-granulate metamaterials
Holger Götz, Thorsten Pöschel, Olfa D'Angelo
Granular media near jamming exhibit fascinating properties, which can be harnessed to create jammed-granulate metamaterials: materials whose characteristics arise not only from the…
Granular binary mixtures improve energy dissipation efficiency of granular dampers
Nydia Roxana Varela-Rosales, Angel Santarossa, Michael Engel +1
Granular dampers are systems used to attenuate undesired vibrations produced by mechanical devices. They consist of cavities filled by granular particles. In this work, we consider…
