摘要
应用FLUENT软件,对2种不同K系数的雾化喷嘴进行了数值模拟计算。分析了不同入口压力方案,得出如下结论:相对于K=0的喷嘴,K=0.3的喷嘴可有效地抑制喷嘴口气穴的形成,提高了喷嘴流量的均匀性,更好地实现了流体的有效雾化。
FLUENT was applied to conduct numerical simulation and calculation on two kinds of atomizing nozzles with different coefficient K. After analyzing schemes with various inlet pressure, such conclusion was obtained： compared with the nozzle with coefficient K of 0, the cavitation at the mouth of the nozzle with coefficient K of 0.3 was effectively restrained, the nozzle flow was more uniform, thus the more effective atomization of fluid realized.
