混流式微泡发生器喷嘴直径对流场影响的研究

摘要

This paper simulated the micro-bubble generators with different radius of jet by using CFD software FLUENT. Took structural parameters of the nozzle radius for example, researched the effects of structural parameters on the performance of micro-bubble generators by changing its parameters to achieve change in the flow field, and basing on speed, turbulence and gas distribution to a comprehensive analysis.%使用计算流体动力学软件FLUENT对微泡发生器内部流场进行仿真分析.以结构参数之一的喷嘴半径为例,通过改变其参数实现流场的改变,基于速度、紊动能和气相分布进行综合分析,研究结构参数变化对微泡发生器性能的影响.
