Foam flow shower

Function

Foam flow is use for the following purposes:

·        Prevent splashing- When a single stream of water hits a surface the water must go somewhere, and because the stream is uniform the water will tend to go mostly in the same direction. If a single stream hits a surface which is curved, then the stream will conform to the shape and be easily redirected with the force of the volume of water falling. Adding the aerator does two things; reduces the volume of falling water which reduces the splash distance, and creates multiple "mini-streams" within the main stream. Each mini-stream, if it were falling by itself would splash or flow in a unique and different way when it hit the surface, as compared to the other mini-streams. Because they are all falling at the same time, the streams will splash in their own way but end up hitting other splash streams. The resulting interference cancels out the majority of the splashing effect.

·        Shaping the water stream coming out of the faucet spout, to produce a straight and evenly pressured stream.

· Conservation of water- Because the aerator limits the water flow through the faucet, water use is reduced as compared to the same time of flow without an aerator. In the case of hot water, because less water is used, less heat energy is used.

·        Reducing nozzle noise

·         Increase water pressure, (often used in homes with low water pressure)

Foam occurs in two basic steps: 

1.Air is drawn into the water stream breaking the stream into a flow of tiny droplets mixed with air.

2. The mixture of air and water passes through a screen, further mixing the air and water and evenly spreading out the resulting stream.
