(54s) Experimental Study of 3D Printed Surface on Granular Mixing in a Rotating Drum

Improving mixing processes in rotating granular flows is still a present issue with typically low productivity and slow rates of mixing achieved in current operation, these problems are further exasperated by the parallel phenomenon of segregation for systems cont particles with different properties. Use of a travelling sinusoidal wave boundary on a circular quasi-2D drum has been proposed as a method of alleviating these issues.Experiments consisting of monodisperse and bi-disperse mixtures of different sizes were tested in both a circular and wavy cross sections at different rotational speeds in order to investigate how an alternative boundary configuration influences flow behavior and mixing dynamics.
