超声驻波悬浮颗粒小球现象的研究

Study on the Phenomenon of Suspended Particles in Ultrasonic Standing Wave

本实验的目的是利用声学原理实现空气中轻小物体的束缚及移动。首先,在分析实验原理的基础上,设计实验方案,制作了三种实验装置,并进行了相关实验研究;其次,在实验研究基础上,采用Comsol仿真软件进行了仿真模拟,绘制声压级图像和流体粒子捕捉动画,并展示了模拟结果;最后,通过理论、实验与模拟结果的对比,对实验结果进行了有效讨论。

The purpose of this experiment is to realize the binding and movement of light and small objects in the air by using acoustic principles.First of all,based on the analysis of the experimental principle,the experimental scheme is designed,three experimental devices are made,and relevant experimental studies are carried out;Secondly,on the basis of experimental research,the Comsol simulation software is used to simulate the sound pressure level image and fluid particle capture animation,and the simulation results are displayed;Finally,through the comparison of theoretical,experimental and simulation results,the experimental results are effectively discussed.
