| 摘 要： | 为了研究气力辅助作用下静电雾化的流场特性,采用粒子图像测速技术（PIV）对风速、荷电电压及通气管与喷头间距等参数影响下的喷雾流场进行测量,并结合Tecplot后处理软件对所储存图片进行处理和分析,获得了不同参数下的静电喷雾流场特性.结果表明：通气管和喷头的间距以及风速一定时,不同的荷电电压形成不同程度的卷吸,且电压越大,卷吸现象越明显,卷吸区域沿着喷雾的轴向逐渐向下延伸;通气管和喷头的间距以及荷电电压一定时,随着风速的增大,气动力的主导作用越来越明显,在气流区的卷吸程度逐渐减弱,卷吸现象逐渐消失,卷吸区域逐渐向喷雾核心区收缩;风速以及荷电电压一定时,随着通气管与喷头间距的拉大,雾滴的漂移现象越来越严重,同时喷雾流场的卷吸现象越来越明显并逐渐向喷雾核心区靠近.

| Abstract: | In order to study the flow characteristics of air-assisted electrostatic spraying,the flow field under the influence of wind speed,charged voltage and space between ventilation pipes and nozzle were measured based on particle image velocimetry(PIV).The images under different parameters were processed by Tecplot software and the flow field was obtained.The results indicated that the entrainment phenomenon is more obvious,entrainment regions extend along the spray axial with the voltage increases when the spa... |
