摘　　要：详细阐述了传统射流微泡发生器的结构和工作原理,且对传统微泡发生器作了结构改进,并对改进后微泡发生器运用流体动力学软件FLUENT采用非结构化网格技术对其内部流场作了分析对比。结果表明,改进后微泡发生器具有较好的流场特性,且改进后锥形碰撞壁具有较好的发泡效果。The structure and working principle of the traditional jet micro - bubble generator are expounded and the structure is improved. Meanwhile, based on the technology of non - structure grid, the flow field of improved micro - bubble generator is analyzed and contrasted. The result indicates that the improved micro - bubble generator has excellent flow field characteristics, and the improved micro - bubble generator with cone - shaped collision wall also has better forth.
