- Abstract:
- The observation of natural rainfall is time-consuming, cost and laboring, artificial rainfall simulation can solve these problems. By measuring, calculating and analyzing rainfall, the rainfall characteristic parameters of Veejet80150 were determined, and the uniformity of the improved trough rainfall simulator was evaluated. The results show that: The rainfall area of Veejet80150 nozzle is rectangular. As the height increase, the rainfall area increase, and the rainfall intensity at the central point decreases. The rainfall intensity of single nozzle decreases regularly from the central point outward, so as to facilitate the combination of multiple nozzles and obtain uniform rainfall in the space. In the case of multiple nozzles combination, the uniformity coefficient of the rainfall simulator at the height of 2.5 m is within the range of 0.88～0.90, and at the height of 4 m is within the range of 0.94～0.95. The rainfall simulator has good uniformity and can meet the best requirements when the nozzle height is great than 2.5 m.
