摘  要：
为研究双侧吸气式增氧机射流器主要结构参数与动力效率的关系,应用正交试验方法,以增氧动力效率E为主要性能指标,选取位置系数R、面积比m、喷嘴收缩角a、喉管长径比β为增氧机射流器主要结构参数,对射流增氧机进行了清水充氧试验。结果表明:各主要结构参数影响增氧动力效率E的主次排序为位置系数、面积比、喷嘴收缩角、喉管长径比;最佳结构参数组合为R=0,m=4,a=30°,β=10。位置系数与面积比之间存在比较显著的交互效应,其显著性低于两者独立作用的水平,高于喷嘴收缩角与喉管长径比的独立作用水平,其他参数之间的交互效应不明显。

摘  要：
Orthogonal experiments were carried out to study the oxygen transfer performance of the dual laterolog aspirating aerator. The work has been focused on the improvement of oxygen-transfer power efficiency with respect to the varying of the aerator's major structural parameters. Effects of single and interaction among them of the four factors on oxygen-transfer power efficiency were investigated respectively. Meanwhile, optimal combination of the four factors on oxygen-transfer power efficiency was presented. It showed an appropriate combination of different factors may improve oxygen-transfer power efficiency effectively. The following summarized the detailed contributions that have been made in the research: ①Ranking of main structural parameters impacting power efficiency is as follows: the location coefficient, section ratio, nozzle angle and throat-pipe aspect ratio. ②Optimized structural parameters that were found in the research are the location coefficient R=0; section ratio m=4; nozzle angle a=30°; pipe aspect ratio β=10. ③There is significantly interactive effect between location coefficient and section ratio.
