The coefficient of restitution is commonly used to describe the collision of a particle either with other particles or with walls and components of plant equipment. The coefficient considers the amount of energy that is dissipated in the collision event. Usually the restitution coefficient is examined by the use of high speed cameras and image velocimetry. In this study a new method based on magnetic particle tracking (MPT) was developed to measure the restitution coefficient of magnetic particles. By performing simultaneous image velocimetry and MPT measurements, the novel approach is validated. The comparison shows a high coincidence of the results from both measurement methods, both for normal direction impacts as well as impacts on oblique surfaces. Furthermore, the rotation of particles was investigated (by rolling down a tilted plate), which has also shown the applicability of the MPT measurement method.en0921-883120221Elsevierhttps://creativecommons.org/licenses/by-nc-nd/4.0/Image velocimetryMagnetic particle trackingRestitution coefficientRotational velocityPhysikTechnikIngenieurwissenschaftenJournal Article10.15480/882.412410.1016/j.apt.2021.11.01410.15480/882.4124Journal Article
