The fully developed flow of air and solid particles in a vertical pipe was calculated using a modified model for particle-eddy interaction in two-phase turbulent flows, which is developed from the particle-source-in-cell model. This model was proposed to account for the effects of the fluctuation frequency spectrum of turbulent gas flow on the motion of particle phase and the influence of particles on the gas turbulent flow. In order to validate this modified model, the flow characteristics of a turbulent upward gas-solid pipe flow was studied both numerically and experimentally. Various combinations of loading and particle diameter were investigated. Velocities of both phases, turbulence intensities, and volume fraction distributions were obtained. The predictions were compared with experimental data measured by the use of a laser Doppler anemometer showing that the overall agreement is good.
