采用LaVision的DaVis 8.0.8图像采集和分析处理软件平台,加上Imager pro HS 4M型相机,构成粒子成像测速(PIV)系统。利用该系统对从一个容器中掉落的圆柱形颗粒的流动分布进行了测量,并与离散元法模型法进行比对,从而优化离散元法模型法
The DEM (Discrete Element Method) is one option for studying the kinematic behaviour of
cylindrical pellets. The DEM experiments attempted to optimize the numerical model parameters that affected time and velocity as a cylindrical vessel emptied. This vessel was filled with cylindrical pellets. Optimization was accomplished by changing the coefficient of friction between particles and selecting the length accuracy grade of the sample cylindrical pellets. The initial state was a series of ten vessel-discharge experiments evaluated using PIV (Particle Image Velocimetry). The cylindrical pellet test samples were described according to their length in three accuracy grades. These cylindrical pellet length accuracy grades were subsequently used in the DEM simulations. The article discusses a comparison of the influence of the length accuracy grade of cylindrical pellets on optimal calibration of time and velocity when the cylindrical vessel is emptied. The accuracy grade of cylindrical pellet
length in the DEM sample plays a significant role in relation to the complexity of a created simulation.
