WebParticle model Kinetic theory models the arrangement and movement of particles in solids, liquids and gases. It explains properties of substances in these different states, and what happens... WebAug 20, 2024 · Models for particle-particle contact conduction, particle-fluid-particle conduction, particle-gas convection, and particle-particle radiation are selected. Model selection is based on model simplicity, acceptance in existing CFD-DEM heat transfer models, extendibility to particles of different sizes, and computational expense.
