The work aims to study the characteristics of pneumatic conveying of wheat grains at the bend. Based on the Euler-Euler two-fluid model, combined with the wall collision friction model, solid stress of particle dynamics and the Gidaspow drag model, a pneumatic conveying model of wheat grains at the bend was constructed. FLUENT was used to numerically simulate the pneumatic conveying process of wheat grains at the bend. The distribution of wheat grain concentration, gas-solid two-phase velocity, shear force between wheat grains and the wall and turbulent kinetic energy of wheat grains in the process of wheat grain flowing through the bend and the straight pipe after the bend were analyzed. The simulation and experimental results showed that the grain phase volume fraction, gas-solid two-phase velocity, grain and wall shear force and turbulent kinetic energy of wheat grains changed with the angle of flow into the bend. Due to the collision and friction among grains and between grains and the wall, the parameters of wheat grains gradually slowed down with the increase of conveying distance after flowing out of the bend. FLUENT software is used to simulate the flow characteristics of wheat grains in the bend, and the reliability of the simulation is verified by experiments. This study combines with the gas-solid two-phase theory and provides a theoretical basis for the design, development and optimization of pneumatic conveying in the bend.
