摘要
在分析单空泡和空泡群簇溃灭压力模型的基础上,通过进口压力对空化数的影响及喷嘴几何结构参数对空化产生和苯酚降解效果的影响来研究淹没水射流装置的空化特性。研究表明,在一定压力范围内,提高进口压力能有效降低空化数;在相同的空化数条件下,角形喷嘴对苯酚的降解效果要优于锥形喷嘴;喷嘴圆柱段在空化活动的产生过程中起着决定性作用,圆柱段长度为8mm,直径为1.2mm的角形喷嘴降解效果最佳。
Through analyzing collapse pressure of single cavity and its clusters,and inlet pressure influence on cavitation number and that of nozzle geometrical parameters on cavitation activity and phenol degradation,the cavitation features of submerged jet device were studied.The research shows that in the range of definite pressure,the rise of inlet pressure can lower cavitation number;and under the condition of the same cavitation number,V-type nozzle outperforms the conical one in degrading phenol,especially the nozzle with a cylindric section of 8mm in length and 1.2mm in diameter because of its decisive role in cavitation.
