IRANJournal Article20070521<em>In the present study saltation velocity of particles during pneumatic conveying was calculated by Computational Fluid Dynamic (CFD). The Lagrangian approach was used for particle motion. The optimum condition in pneumatic conveying is achieved by minimum energy loss. The gas and particle motion equations were solved using a finite volume discretisation and Runge-Kutta schemes respectively. The results of CFD simulations and experimental correlation for uniform particles are in good agreement (average error 17.6%). In order to study the effect of Particle Size Distribution (PSD) on saltation velocity the real PSD of injected pre- polymer into gas phase polymerization reactor was used.</em><em>In the present study saltation velocity of particles during pneumatic conveying was calculated by Computational Fluid Dynamic (CFD).
