Particle-level Simulation of Magnetorheological Fluids: A Fully-Resolved Solver
International Journal of Multiphase Flow, 2023 Magnetorheological fluids (MRFs) are smart materials consisting of micro-scale magnetizable particles suspended in a carrier fluid. The rheological properties of a MRF can be changed from a fluid-state to a solid-state upon the application of an external magnetic field. This study reports the development of a particle-level simulation code for magnetic

A coupled SPH-DEM approach for modeling of free-surface debris flows
AIP Advances, 2022 A Lagrangian mesh-less model is proposed to simulate fluid–solid flows with multiple-sized solids, i.e., millimeter-sized particle and larger-sized debris.

Analysis of Mobility Effects in Particle‐Gas Flows by Particle‐Resolved LBM‐DEM Simulations [PDF]
Chemie Ingenieur Technik, 2020 AbstractParticle‐resolved direct numerical simulations are performed to simulate the flow through particle assemblies that are either static or freely moving to demonstrate the influence of particle mobility. To obtain a comprehensive understanding for this influence essential parameters such as the Reynolds number, solids volume fraction, particle ...

Communications Physics, 2023 Particle-in-cell (PIC) simulations are a widely-used tool to model kinetics-dominated plasmas in ultrarelativistic laser-solid interactions (dimensionless vectorpotential a 0 > 1). However, interactions approaching subrelativistic laser intensities (a 0 ≲

Resolved simulations of single iron particle combustion and the release of nano-particles
Proceedings of the Combustion Institute, 2023 We present a numerical study of the combustion of single iron particles in an O 2-N 2 atmosphere. By resolving the full boundary layer, mass and heat transfer are accurately modeled, including Stefan flow. Only the conversion of Fe to FeO is taken into account and evaporation is implemented to investigate the formation of nano-sized iron-oxides ...

Impact of vibrationally resolved H2 on particle balance in Eirene simulations [PDF]
Contributions to Plasma Physics, 2022 AbstractTo evaluate the impact of transport of metastable, vibrationally excited states of the hydrogen molecule in dense and cold plasmas each vibrational state must be simulated as an individual species. Eirene neutral gas simulations of a one‐dimensional flux‐tube using a metastable‐resolved model indicate a 30–50% decrease in the effective ...

High-resolution simulations of turbidity currents
Progress in Earth and Planetary Science, 2017 We employ direct numerical simulations of the three-dimensional Navier-Stokes equations, based on a continuum formulation for the sediment concentration, to investigate the physics of turbidity currents in complex situations, such as when they interact ...
