Fluid-particle systems are highly sensitive to particle morphologies. While many attempts have been made on shape descriptors and coupling schemes, how to simulate the particle-particle and particle-fluid interactions with a balance between accuracy and efficiency is still a challenge, especially when complex-shaped particles are considered. This study presents a Metaball-Imaging (MI) based Discrete Element Lattice Boltzmann Method (DELBM) for fluid simulations with irregular shaped particles…

Particle morphology plays a key role in affecting physical and mechanical behaviors of granular media. While various mathematical approaches and shape descriptors have been proposed to describe the

Efficient implementation of superquadric particles in Discrete Element Method within an open-source framework

An efficient C++ implementation of superquadric particles within the open-source and parallel DEM package LIGGGHTS is presented and adequacy of the super quadric shape model and robustness of the implemented superquadrics DEM code are shown.

Lattice Boltzmann simulations of settling behaviors of irregularly shaped particles.

It was found that a minor change in the starting projected area, an indicator of the initial particle orientation, would not strongly affect the settling velocity for low Re, and periodic oscillations developed for all simulated particles when Re>100, and the periods were not sensitive to Re.
