Flow Shape of Water Bell
When the water flowing from the nozzle collides on the fixed disc, the water spread horizontally on the disc. As a result, the hemispherical water film is formed. Because of the water film to be shaped like a bell, this flow phenomenon is called the water bell. For the beauty of the flow shape, it is mainly used for the fountain devices such as the park and the landscaping. However, the basic experimental reports on the characteristics for the flow shape of the water bell are not much seen. Therefore, it was classified into two types of the flow shape as basic data for controlling the flow shape of the water bell. In addition, it was investigated experimentally the characteristics of the diameter, the outflow angle and the film thickness of the water bell for the impact velocity, the flow rate and the collision disc diameter.
