Abstract
Reports that implementation of kinetic theory for granular flows added strength to the two-phase flow model in a mini-riser.
The model uses Fluent simulation software simulate the mini-riser with 0.012m ID and 3m height. The Euler-Euler two fluid model was adopted in two dimensional numerical simulation.  Solid stress was calculated based on granular temperature and granular viscosity obtained through simulation. Simulation results, including solid phase fraction and solid phase velocity, are well aligned with experimental results.
