| Abstract: | 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. |
