Abstract

CFD simulation using Eulerian-Eulerian approach is performed for gas-solid flows in horizontal and vertical pipes. The
Gidaspow drag model with algebraic granular temperature model were used for the simulation. The algebraic model is
the simplified one to model the granular temperature and it speeds up the convergence in two phase flow unsteady
simulations. Numerical predictions are compared with experimental data and good agreement was found for vertical
flows. The model predicts the gas velocity correctly, but couldn’t predict the solid phase velocity in horizontal flows.
Vertical flow has symmetrical profiles for velocity, volume fraction and other flow parameters; whereas the asymmetric
flow occurs in horizontal flows.
