Modeling of Gas-Solid Turbulence Flow in Silo

Modeling of Gas-Solid Turbulence Flow in Silo

This paper presents a computational fluid dynamics (CFD) study of gas-solid turbulence flow in a silo. The simulations were performed using three different turbulent models namely, standard k-ε (SKE), RNG k-ε (RNG) and Realizable k-ε (RKE). The gravitational force, Saffman lift force and two-way cou...
