Heat Transfer in Flows of Granular Materials

Cts-9530357 Hunt，Melany L.The PI建议研究颗粒物质流动中的热传递和摩擦加热。将建造两个实验装置，一个涉及槽流，另一个处理环状流，以模拟这些现象。将使用离散元素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、化学工业以及其他各种应用中都很重要，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.
