Heat Transfer in Flows of Granular Materials

Hunt, Melany L. PI提出研究颗粒物料流动中的传热和摩擦加热。两个实验装置，一个涉及通道流动和另一个处理环形流动，将建立模拟这些现象。将使用离散元计算机模拟来跟踪单个粒子的轨迹及其相互作用。颗粒流在食品加工业、化学工业和各种其他应用中都很重要，例如药品、农药和火药的流动。

Abstract CTS-9530357 Hunt, Melany L. The PI proposes to study heat transfer and frictional heating in the flow of granular materials. Two experimental apparati, one involving channel flow and the other treating annular flow, will be constructed to model these phenomena. A discrete-element computer simulation will be used to track the trajectories of individual particles and their interactions. Granular flow is important in the food processing industry, in the chemical industry, and in a variety of other applications, such as the flow of pharmaceuticals, pesticides, and gunpowder.
