摘要：

Multiphase flow are involved in many fields in natural phenomenon as well as industrial applications. Drag coefficient is an important parameter in the modelling and simulation of multiphase flow. Non-sphere particles are usually simplified to sphere particles in multiphase flow simulation. However, non-sphere particles are more common in practice. Hence, it is significant to investigate shape effects on the drag coefficient of non-sphere particles. This article selects several typical shapes of particles as research objects. 3-D printers are used to build particle models. And high speed cameras are used in record the whole process of particle settling. Detailed information of particle path and speed are gotten through image processing of high speed cameras.
