摘　　要：基于OpenFOAM开源软件,利用PIC算法开发了V型选粉机的高效仿真工具,验证了其在V型选粉机压降和颗粒分级效率预测上具有高精度和可靠性优势。单因素研究发现,V型选粉机打散板主要影响设备压降,分级板显著影响颗粒分级效率,入口风速提升能有效提高颗粒分级效率但会增加压降。多因素分析明确了优先调整打散板角度和封闭情况的能耗优化路径,以及以优化分级板角度和间距为主的分级效率优化实施路径,实现了模型的定制化开发,为摆脱对国外技术的依赖、实现仿真工具自主可控提供了重要技术支撑。A high-efficiency simulation tool for the V-type powder separator was developed using the PIC(Particle-in-Cell) method within the Open FOAM open-source software.The tool was validated for its high accuracy and reliability in predicting pressure drop and particle classification efficiency in Vtype powder separators.Single-factor studies revealed that the dispersion plate primarily affects the equipment's pressure drop,while the classification plate significantly impacts particle classification efficiency.Increasing the inlet air velocity effectively enhances classification efficiency but also leads to a higher pressure drop.Multi-factor analysis identified two optimization pathways:adjusting the dispersion plate angle and closure state to minimize energy consumption,and optimizing the classification plate angle and spacing to maximize classification efficiency.This study enabled the customized development of a simulation model,providing a crucial technological foundation for reducing dependence on foreign technologies and achieving independent control over simulation tools.
