According to the application of this principle,the pressure,temperature and velocity's distribution are analyzed with FLUENT software. Optimal designing structure of the nozzle is:Inlet diameter:D1=15.2mm;outlet diameter:D2=13mm;throat radius:Rcr= 3.5mm;Diverging angle:α=30°;L1=20.9mm;expanding angle:β=10°;L2=50mm; Total length:L=70.9mm.
跟据上述原理应用FLUENT软件对喷枪内的压强、温度、速度的分布做分析后,设计出最优的喷枪结构为:入口直径D_1=15.2mm,出口直径D_2=13mm,喉部半径R_(cr)=3.5mm;渐缩角α=30°,长度L_1=20.9mm;渐扩角β=10°,渐扩段长度L_2=50mm;总长L=70.9mm。
