非规则形状颗粒自由沉降监测分析系统

Monitoring and analysis system for free settling of irregular shape particles

流体力学中传统的颗粒沉降行为研究大多针对规则球形颗粒,而异形颗粒的沉降问题易被忽视。该文基于高速摄像-Python-MATLAB技术设计了异形颗粒沉降监测分析系统,主要由沉降装置、高速摄像机、计算分析系统等组成,可以对不同形状颗粒在液体介质中的沉降行为进行快速、精准的记录和多角度分析。该系统的设计和教学实践有助于提升学生对特殊现象的观察与捕捉能力,以及解决科学问题的能力。

Most traditional researches on particle settlement behavior in fluid mechanics focus on regular spherical particles,but the settlement of irregular particles is easily ignored.Based on high-speed camera-Python-MATLAB technology,this paper designs a monitoring and analysis system for special-shaped particle settling,which is mainly composed of a settling device,high-speed camera,and calculation and analysis system,which can quickly and accurately record and analyze the settling behaviour of particles of different shapes in liquid media.The design and teaching practice of the system help improve students'ability to observe and capture unique phenomena and solve scientific problems.
