摘要
利用混合有限分析法(HFAM)及k ε紊流模型对超小面积比(面积比为1.326)的同轴受限射流流动进行了数值模拟,得到了不同速度比下速度剖面和流线的分布,分析了速度比对回流的发生及其位置的影响.
Hybrid finite analytical method (HFAM) and k-ε turbulence model are applied to the numerical simulation for the confined coaxial jets of super small area ratio. The calculated velocity profiles in different velocity ratio fit well with the experimental data. Also, distribution of streamlines in different velocity ratio is obtained. It is found that the velocity ratio has great effect on the occurrence of recirculation and its location.
