Mehrlochdüse

A Mehrlochdüse, meaning "multi-hole nozzle" in German, is a type of nozzle designed with multiple outlets for fluid ejection. Unlike a single-hole nozzle that expels a fluid stream from one aperture, a Mehrlochdüse distributes the fluid across several smaller openings. This design can influence the flow characteristics, such as the spray pattern, droplet size distribution, and the overall momentum transfer.

The specific arrangement, size, and shape of the individual holes in a Mehrlochdüse are crucial to its performance. These parameters can be engineered to achieve a desired effect. For example, in atomization processes, a multi-hole design can lead to finer droplets or a broader spray cone compared to a single orifice of equivalent total area. This is often due to increased shear forces and breakup mechanisms facilitated by the multiple jets.

Applications for Mehrlochdüsen are diverse. They are commonly found in combustion systems, such as fuel injectors for engines, where precise atomization is critical for efficient burning. They can also be utilized in spraying technologies for agricultural or industrial purposes, in cleaning devices, and in certain types of injectors for medical or laboratory equipment. The ability to control the spray characteristics makes the Mehrlochdüse a versatile component in fluid dynamics engineering.
