| 摘 要： | 为认知水泥砂浆混合物料靠重力自由流出的流动状态,对包装机出口处料仓内的水泥砂浆混合物的三维定常流场进行了数值模拟。考虑到物料在料仓内流动时是密实状态,因此简化为流体模型进行分析,同时综合考虑了混合物料所受重力和内摩擦力对流动性能的影响。模拟结果直观显示了料仓内的速度和流线等特征,研究结果对研究背压式水泥砂浆包装机的设计与改进提供了一定的理论指导。

| Abstract: | To learn the gravity flowage condition of cement-sand mix, the three-dimensional stationary flow field of cement-sand mix in the storage hopper of packer is simulated numerically. Considering the material is in dense condition when it flows, it is simplified as fluid to analyze. Besides, the impact of internal friction over flowing property is included. The simulation result illustrates the velocity and streamline of material in the storage hopper, which provides theory guidance for the design and improve o... |
