Analysis of Salt-bath Scaled Model on Horizontal Cold Jet Effected by Vertical Thermal Plume in Large Space
Based on the similarity theory, a box containing liquid aimed to model the indoor air distribution in a large space building was constructed, and the liquid experiments were taken to explore the pattern of the effect of the vertical developing plumes on the horizontal jets in large space buildings....

| description | Based on the similarity theory, a box containing liquid aimed to model the indoor air distribution in a large space building was constructed, and the liquid experiments were taken to explore the pattern of the effect of the vertical developing plumes on the horizontal jets in large space buildings. The velocity ratio of the model to the prototype was taken to figure out the similarity between the cold jets and the thermal plumes. The results of the experiments show that, under the effect of the vertical developing plumes, the motion curve of the horizontal jets deviated upward. The single plume has little effect on the forepart before the countering point of the plume and jet. The raising of the jet curve is in the terminal of the cold jet. Under the effect of the two plumes, the deviation of a single jet increased. The deviation of the jet curve differs with the countering point of the plumes and the jet changing. In the forepart of the jet, the initial force of the jet predominates, thus the curve is not easy to deviate. However, in the terminal of the jet, the initial force of the jet weakens, and the curve is easy to be disturbed by the plume. Compared with the effect of different plumes, the effect of two plumes on the motion of the single jet weakens after two jets interact. |
