论文摘要
在颗粒的气动运输过程中形成的沉积物是工业设施中经常发生爆炸的根源。因此，为了促进工厂的运营安全性，我们通过新的实验测试 - 探索粉末流的沉积物形成。为此，使用方形透明管作为测量部分对粒子流进行光学分析。我们表征了沉积模式，并根据流量条件定量了沉积物的分数。所考虑的参数包括雷诺数，粉末载荷，管道材料和环境条件（温度，湿度）。更具体地说，我们研究了多分散PMMA颗粒通过由PMMA和PC制成的管道的运输。
Deposits which form during the pneumatic transport of particles are a frequent source of explosions in industrial facilities. Thus, to contribute to the operational safety of industrial plants, we explore the deposit formation of powder flows with our new experimental test-rig. To this end, the particle flow was analyzed optically using a square-shaped transparent pipe as a measuring section. We characterized the deposit pattern and quantified the fraction of particles that deposit depending on the flow conditions. The parameters under consideration included the flow Reynolds number, the powder loading, the duct material, and the ambient conditions (temperature, humidity). More specifically, we investigated the transport of polydisperse PMMA particles through pipes made of PMMA and PC.
