中文摘要:为探索纸质被动式农药微混合器的主要参数对农药混合效果的影响规律和增强农药混合的机理,选取Y型、Z型和方波型3种结构的纸质被动式农药微混合器,试验研究了每种微混合器不同参数条件对混合性能的影响,选出最优参数,再将最优参数下的3种微混合器的混合性能进行对比。试验结果表明,Y型微混合器的最优参数为:入口速度0.010mL/min、入口角30°,Z型微混合器的最优参数为:入口速度0.010mL/min、峰间距3mm、转角30°,方波型微混合器的最优参数为:入口速度0.010mL/min、波高2mm、波宽5mm;在各自的最优参数条件下,Y型微混合器出口处混合强度为0.6227,Z型微混合器出口处混合强度为0.6902,方波型微混合器出口处混合强度为0.7326,方波型微混合器混合性能最好;纸质被动式农药微混合器通道内部存在纸纤维,可以提供流体流动的动力,也可以加剧分子间的扩散作用,同时也在一定程度上限制了对流作用。

Abstract:In order to discover the influence rules of paper based passive micro mixer’s parameters on mixing effect of pesticides, the Y shaped micro mixer, Z shaped micro mixer, square wave micro mixer were selected and the relationships among the parameters of each kind micro mixer and mixing performance by experiments were researched. Then optimal parameters of each kind micro mixer were chosen, and mixing performances of three micro mixers were contrasted under the optimal parameters. The results of experiments show that Y shaped micro mixer’s optimal parameters are inlet velocity of 0.010mL/min, inlet angle of 30°, Z shaped micro mixer’s optimal parameters are inlet velocity of 0.010mL/min, peak separation of 3mm, corner angle of 30°, square wave micro mixer’s optimal parameters are inlet velocity of 0.010mL/min, wave height of 2mm, wave width of 5mm, and under their optimal parameters, Y shaped micro mixer’s outlet mixing intensity is 0.6227, Z shaped micro mixer’s outlet mixing intensity is 0.6902, square wave micro mixer’s outlet mixing intensity is 0.7326. The square wave micro mixer has the best mixing performance. Paper based passive micro mixer has some fibers in its channel, it can provide dynamic of flowing and enhance the diffusion of liquid pesticides. On the other hand, it can limit the convection to a certain degree. This article researched the mixing performance of paper based passive micro mixer for the first time internationally.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
