In this study, a numerical approach is employed to investigate the flow and energy transitions characteristics of particles in a horizontal drum equipped with rotational flat blade. The results indicated that the dominant energy dissipation mechanisms were the internal friction between particles, the friction between particles and wall, and the damping loss of collision between particles. The mean tangential velocity and blade torque increased monotonously with the increase of fill level and blade speed. The dimensionless mean velocity in the tangential direction was dependent on the fill level and mill geometry instead of impeller agitation rate. In sequence, the characteristic parameters related to the geometric features and operational conditions were established to characterize the energy input in the agitator. The blade torque was characterized as a linear function of the characteristic parameter T_S, which is determined by mill geometry and operational conditions.

在这项研究中，采用数值方法研究装有旋转平叶片的水平滚筒中颗粒的流动和能量转换特性。结果表明，占主导地位的能量耗散机制是颗粒之间的内摩擦、颗粒与壁面的摩擦以及颗粒之间碰撞的阻尼损失。平均切向速度和叶片扭矩随着料位和叶片速度的增加而单调增加。切线方向的无量纲平均速度取决于填充水平和磨机几何形状，而不是叶轮搅拌速率。依次建立与几何特征和操作条件相关的特征参数来表征搅拌器中的能量输入。T _S，由轧机几何形状和操作条件决定。
