基于CFX的磨料水射流喷嘴的流场分析

摘要

According to the two kinds of structure with the abrasive water jet nozzle,and the standard κ-ε model,numerical simulation was proceed by using the fluid mechanics software CFX.The result shows that the solid phase velocity provided by cone straight nozzle is higher than that of conical nozzle when jet conditions is constant,and it is more suitable for abrasive jet incision.%针对2种结构的磨料水射流喷嘴,采用标准的k-ε模型,利用流体力学软件CFX进行数值模拟.结果表明:当射流条件一定时,锥直形喷嘴提供的固相速度高于锥形喷嘴固相的喷出速度,更加适合磨料射流切割.
