Almost every physical item we use in our daily lives at some point requires the transport and handling of powdered or granular materials during the manufacturing process. Be it food (sugar, flour), chemicals (soap powders, detergents), cosmetics (talc, face powder) or electricity generation (coal and ash); each of these industries uses the flexibility of pipeline systems to transport powders and granular solids using air as the motive force. However, the cost of poor design and the inaccurate prediction of system performance adversely affect the efficiency of many industries. Improvements to the accuracy of gas-solid flow modeling particularly for low velocity dense phase systems will have a direct impact on manufacturing efficiency.

我们在日常生活中使用的几乎每一件物理物品在制造过程中都需要运输和处理粉末或颗粒材料。无论是食品（糖、面粉）、化学品（肥皂粉、洗涤剂）、化妆品（滑石粉、爽身粉）还是发电（煤和灰），这些行业都利用管道系统的灵活性，以空气为动力输送粉末和颗粒状固体。 然而，不良设计的成本和对系统性能的不准确预测对许多行业的效率产生了不利影响。 提高气固两相流动模型的精度，特别是低速密相系统的精度，将直接影响生产效率。
