Verification of the EMMS Model with Pseudo-Particle Modeling

Abstract

A bottom-up simulation method, pseudo-particle modeling (PPM), is used to reproduce fluidization phenomena from first principles, that is, Newton’s laws of motion, and measure and analyze the energy dissipation in different systems. An asymptotic behavior in the energy consumed to transport and suspend particles per unit mass, N st, is observed in the evolution of the systems, thereby verifying the stability condition. The scale-dependence of this behavior is also studied, allowing the appropriate spatio-temporal range of the EMMS model to be defined. The behavior of the stability condition at different particle-fluid density ratios is also investigated.
