摘要：

The process of dense phase pneumatic conveying gypsum in stepped pipeline was simulated by using an Euler-Euler two fluid model of dense gas-particle two phase flow based on the kinetic theory of gas and granular. The simulation results showed dynamic pressure increased while static pressure decreased in the first two tapered pipe, but this trend became opposite in the last diffuser pipe. The gas and particle velocity both increased in the 80-65mm and 65-50mm tapered pipe, but decreased in 50-80mm diffuser pipe. In a short, the results showed that the simulation was consistent with the fact, which proved the feasibility of our simulation.
