Discrete phase method (DPM) model was used to analyse rotary drum systems for segregation behavior. DPM simulations were performed for comparison with a dynamic segregation experimental measurement from the literature. This included dynamic segregation and time-averaged particle velocity field, which were validated with experimental data. In addition, a direct DPM and parcel scaled DPM simulation study was performed to analyse the effect of drum and particle parcel size scaling. The segregation dynamics was evaluated using the Lacey mixing index. This work shows segregation dynamics decreases with increasing drum size while keeping the same particle size. It further shows that for a given drum size the segregation dynamics deviate after a certain particle parcel scaling limit. The parcel scaling limit also increases with increasing drum size.

离散相法 (DPM) 模型用于分析转鼓系统的离析行为。进行 DPM 模拟以与文献中的动态分离实验测量进行比较。这包括动态分离和时间平均粒子速度场，这些都用实验数据进行了验证。此外，还进行了直接 DPM 和包裹缩放的 DPM 模拟研究，以分析鼓和颗粒包裹尺寸缩放的影响。使用 Lacey 混合指数评估离析动力学。这项工作表明分离动力学随着鼓尺寸的增加而降低，同时保持相同的颗粒尺寸。它进一步表明，对于给定的鼓尺寸，分离动力学在特定颗粒包裹缩放限制后偏离。包裹缩放限制也随着滚筒尺寸的增加而增加。
