Flüssigkeitsstrahl

A Flüssigkeitsstrahl, or liquid jet, is a stream of liquid ejected from an orifice or nozzle under pressure. The behavior of a liquid jet is governed by principles of fluid dynamics, including surface tension, viscosity, and inertia. When a liquid exits a nozzle, it forms a coherent stream that can travel a significant distance before breaking up into droplets. This breakup is often influenced by factors such as the jet's velocity, the surrounding medium's density and viscosity, and the presence of external forces like gravity or air resistance.

The formation of a liquid jet can be observed in various natural phenomena and technological applications. Examples include water fountains, waterfalls, and the spraying of liquids in agricultural or industrial processes. In engineering, liquid jets are utilized in cutting tools, cleaning systems, and inkjet printing. The precise control of jet characteristics, such as diameter, velocity, and spray pattern, is crucial for optimizing performance in these applications. The study of liquid jets often involves analyzing phenomena like jet instability, droplet formation, and the impact of the jet on surfaces.
