The water distribution in a natural draft wet cooling tower (NDWCT) has great effect on the performance of cooling tower. This paper presents a three-dimensional two-phase simulation of flow field below a single spray nozzle with particular emphasis on the water distribution. The standard к-ε model has been utilized in the CFD model. The simulation has adopted the Eulerian approach for both the air phase and water phase. The results show the non-uniform profile of water distribution across the radius of computational domain. The structures of the spitting device should be improved to get better distribution of sprayed water.
