LIGGGHTS-INL: Biomass Particle Simulation and Modeling

LIGGGHTS-INL is an extended version of LIGGGHTS, an Open Source Particle Simulation Software. LIGGGHTS is based on LAMMPS, a widely used molecular dynamics simulator. LIGGGHTS aims to improve the capability of LAMMPS for industrial applications, specifically in biomass particle flow modeling. The software will be kept open-source and free to use for the general public. The goal is to address process upsets in biomass feedstock handling, such as jamming and clogging, which hinder the cost reduction and market competitiveness of biofuels. Our innovation lies in developing laboratory experiment-informed/validated, semi-empirical mechanistic laws for biomass particles and implementing them in the software. We benefit from the support of INL’s Biomass Feedstock National User Facility (BFNUF) for experimental validation. Our solution offers numerical predictability of granular biomass flow and serves as a valuable design tool for biomass feedstock handling equipment optimization.
