摘要
利用雷诺应力模型对同向流动环境中3孔热水浮射流进行数值模拟,得出了不同流速比下的速度场,温度场,并对结果进行了对比分析。探讨了不同流速比时各股射流之间的相互影响,最后得出3种流速比下的射流轨迹线。
With reference to the model of Reynolds Stress Model, the paper simulated the buoyant jets of thermal water at the different velocity ratio in co - flowing. Intensity of velocity field, temperature field under any condition, and the contrastive analysis to the numerical simulation result was carried on. The interaction among the jets of different velocity ratio were discussed. Finally get the jet trochoid at different velocity ratio.
