In order to investigate the impact of drill pipe rotation on coal particles transport efficiency during negative pressure sampling,CFD and DEM were used to explore the effects of drill pipe rotational speed and coal particles mass flow rate on gas-solid flow characteristics. The results show that:the maximum axial airflow velocity inside the drill pipe decreases and stabilizes as the transport distance increases,while the maximum tangential velocity rapidly decays and vanishes. As rotational speed increases,the axial airflow velocity remains largely unchanged,but the tangential velocity significantly increases. With higher rotational speed,the spiral flow of coal particles becomes more pronounced,the length of the vortex region increases,and the length of the suspension region decreases. The number of coal particles entering the drill pipe decreases,and the distribution of particles above 5 m/s increases and becomes more dispersed. During rotation,the actual solid-to-gas ratio inside the drill pipe is lower than the set value,and coal particles transport efficiency increases and then decreases with the rise in rotational speed.

为探究负压取样过程中钻杆内煤屑-气流动特性,采用计算流体力学与离散单元法(CFD-DEM)耦合模拟法探讨钻杆转速、煤屑质量流量对煤屑输送过程中气固流动速度分布及煤屑输送效率的影响特征。结果表明:钻杆内气流最大轴向速度随着输送距离的增加而逐渐减小并趋于稳定,最大切向速度迅速衰减并消失;钻杆转速增加时,气流最大轴向速度变化不大,最大切向速度显著增加;随着钻杆转速增加,煤屑螺旋流更加明显,旋流区距离变长,悬浮区距离变短;进入钻杆的煤屑数量减少,5 m/s速度以上的煤屑分布增多且分散;转动时钻杆内部实际固气比小于设定值,煤屑输送效率随转速的提高先增后减。
