Shape matters: Competing mechanisms of particle shape segregation
D. Hernández-Delfin, D. R. Tunuguntla, T. Weinhart +2
It is well-known that granular mixtures that differ in size or shape segregate when sheared. In the past, two mechanisms have been proposed to describe this effect, and it is uncle…
The influence of material properties and process parameters on the spreading process in additive manufacturing
Mohamad Yousef Shaheen, Anthony R. Thornton, Stefan Luding +1
Laser powder bed fusion (LPBF) is an additive manufacturing (AM) technology. To achieve high product quality, the powder is best spread as a uniform, dense layer. The challenge for…
Surface flow profiles for dry and wet granular materials by Particle Tracking Velocimetry; the effect of wall roughness
Sudeshna Roy, Bert J. Scheper, Harmen Polman +4
Two-dimensional Particle Tracking Velocimetry (PTV) is a promising technique to study the behaviour of granular flows. The aim is to experimentally determine the free surface width…
Micro-macro transition and simplified contact models for wet granular materials
Sudeshna Roy, Abhinendra Singh, Stefan Luding +1
Wet granular materials in a quasi-static steady state shear flow have been studied with discrete particle simulations. Macroscopic quantities, consistent with the conservation laws…
Granular flow over inclined channels with linear contraction
D. R. Tunuguntla, T. Weinhart, A. R. Thornton +1
We consider dry granular flow down an inclined chute with a localised contraction theoretically and numerically. The flow regimes are predicted through a novel extended one-dimensi…
