Comparison ofexperimental and simulation results for turbulent gas-solid riser flow

Paper in proceeding, 2008

This paper compares measurements of the radial solids concentration in a riser with CFD simulations. An Eulerian model based upon the kinetic theory for granular flow, extended with models describing turbulence modulation and dispersion, is used to treat the particulate phase. Coupling between momentum equations of the gas and particulate phases is taken into account via a mean drag force formulation. Solids distribution profiles over three horizontal planes are measured by the use of optical probes. The pressure drop is used to estimate an average solids concentration profile along the riser. The comparison is reported for a single superficial gas velocity and solids mass flux.
