中文摘要	With the fast development of urbanization in China, the urban thermal environment has been worsen due to the more and more obvious heat island phenomena. Aartificial waterscape is regarded as one of the most effective methods to improve the outdoor climate. In this paper a fountain model is developped based on experiment results and Particle-Source-In Cell (PSI-CELL) model. Lagrangian approach is adopted to simulate the dynamics properties of droplets in the air while Eulerian approach is employed to solve the conservation equations of the air. The droplet size and velocity distributions are calculated based on the atomization property of the pressure pipe nozzle. The predicted results have been compared against the experiment values. The resulting inaccuracy can be traced back to the change of prevailing wind direction and velocity changes as also as the atomization analysis. Finally the affected factors have been discussed.; Tsinghua Univ
