摘要
从驻波场强迫振动下乳化液中水滴的受力分析出发,建立了驻波场下液滴运动速度模型,利用Matlab仿真分析了水滴在驻波场中的运动规律,同时,分析了水滴位置、水滴粒径与驻波频率对水滴速度的影响。仿真结果表明:水滴具有向波节运动的趋势,其初始位置与波节距离越远,到达波节的时间就越长;半波长范围内,水滴运动速度呈正弦分布;水滴粒径越大,波动越明显,波动时间越长。
Based on the stress analysis of water droplets in emulsion under the forced vibration of a standing wave field,this paper elaborated the establishing of velocity model of droplets movement,which was analyzed with Matlab.At the same time,the influences of droplets＇ position,diameter and frequency on the droplet velocity were analyzed too.Findings of the simulation indicated the evidence of droplets moving towards the nodes of standing wave;within range of half-wavelength,droplets velocity changed with a sinusoidal pattern,and the bigger the droplets,the more evidently they moved back and forth with longer vibration time.
