The Mechanisms determining the Rolling Motions of Bodies

本计画旨在探讨影响球体及圆柱体滚动运动之机制。这个国际项目希望通过新的实验和计算方法产生关于表面粗糙度、空化和可压缩性影响的新知识。 该项目的预期成果包括发现表面粗糙度在允许物体滚动中的明确作用、修改这些运动的方法、导致物体振动的尾流机制以及由滚动体引起的混合。这将为理解粒子和物体在诸如粒子反应器和沉降过程等一系列情况下的运动提供显著的益处。

This project aims to investigate the mechanisms affecting the rolling motions of spheres and cylinders. This international project expects to generate new knowledge of the effect of surface roughness, cavitation and compressibility using novel experimental and computational methods. Expected outcomes of this project include the discovery of the explicit role of surface roughness in allowing bodies to roll, the means of modifying these motions, the wake mechanisms leading to body vibration, and the mixing induced by rolling bodies. This will provide significant benefits to the understanding of the motion of particles and bodies in a range of situations such as particle reactors and sedimentation processes.
