摘要
利用液滴撞击聚四氟乙烯摩擦引起的电荷转移的原理,设计并制作了一种液滴式发电装置,并探究了相关参数对其发电量的影响.研究结果显示,发电量与液滴的下落高度、溶液浓度、温度密切相关.当液滴下降高度为 30 cm时,发电量达到峰值且发电效率达到最大.氯化钠液滴溶液浓度越大,发电量越小,发电效率越低.液滴温度的越高,发电量和发电效率呈增加趋势.同时还发现液滴大小和被撞击的导电玻璃的几何尺寸也会影响发电量和发电效率.
Abstract
A droplet-based power generation device was designed and fabricated,utilizing the principle of charge transfer induced by droplet impact on polytetrafluoroethylene(PTFE)friction.The influence of various parameters on power generation was investigated.The results show that power generation is closely related to the droplet's fall height,solution concentration,and temperature.When the droplet fall height is 30cm,the power generation reaches its peak,and the power generation efficiency is maximized.The higher the concentration of sodium chloride solution,the lower the power generation and efficiency.As the droplet temperature increases,both power generation and efficiency show an increasing trend.It was also found that the size of the droplets and the geometric dimensions of the impacted conductive glass affect power generation and efficiency.
