Numerical simulation of pneumatic conveying

It has been shown that modified k e model can be used to describe the turbulent kinetic energy of gas phase; kinetic fluctuation transport equation of granular flow can be used for that of particle phase, and a physical model and numerical simulation of pneumatic conveying have been established. Both dilute and dense conveying processes in vertical pipe has been predicted by using developed model. The mean gas velocity distribution, particle velocity distribution as well as pressure drop have been studied in different loading ratio of particles to gas. The results of the numerical simulation coincide with available experimental data to indicate that the flow patterns for both phases and pressure drop obtained in the present work are satisfied.
