Abstract We study the effects of fluid–particle and particle–particle interactions in a three-dimensional monodispersed reactor with unstable fluidization. Simulations were conducted using the immersed boundary method for particle Reynolds numbers of 20–70 with an Archimedes number of 23 600. Two different flow regimes were identified as a function of the particle Reynolds number. For low particle Reynolds numbers ($20 < Re_p < 40$), the porosity is relatively low and the particle dynamics are…

Particle – wall collisions in a viscous fluid

This paper presents experimental measurements of the approach and rebound of a particle colliding with a wall in a viscous fluid. The particle’s trajectory was controlled by setting the initial

Collision model for fully resolved simulations of flows laden with finite-size particles.

TLDR
A collision model for particle-particle and particle-wall interactions in interface-resolved simulations of particle-laden flows and is physically realistic, provided that the prescribed collision time is much smaller than the characteristic time scale of particle motion.
