在求解连续气相流场计算收敛的基础上引入离散相,通过相间耦合计算得到不同粒径的喷射源颗粒以速度20m/s、质量流量0.005kg/s进入摩擦器后的运动轨迹、速度场及浓度场的分布情况。研究摩擦器内气固两相流场的分布情况,为摩擦器优化设计及摩擦电选研究奠定了理论基础。
The discrete phase was introduced on the basis of solving the calculation of the convergence of the continuous gas flow field. The motion trajectory and velocity field of the particles with different diameters after entering the friction device at a speed of 20 m / s and a mass flow rate of 0.005 kg / s were calculated by phase coupling Concentration field distribution. The distribution of gas-solid two-phase flow field in a friction stirrer is studied, which lays a theoretical foundation for the optimal design of a friction stirrer and the study of tribocharging.
