Düsenwinkel

Düsenwinkel is a term used in engineering and physics to describe the angular characteristics of a jet exiting a nozzle. In a broad sense it refers to the angle at which the jet spreads away from the nozzle axis, or the angular distribution of the spray produced by a nozzle. The precise meaning can vary by discipline: in fluid mechanics it is often connected to the divergence of the jet, while in spray technology it denotes the spray angle that defines the width of the reach of droplets.

In practice, the Düsenwinkel is determined by the nozzle design and operation conditions, including the geometry of the nozzle outlet (for example, flat-fan, hollow-cone or solid-cone configurations), the pressure ratio, fluid properties such as viscosity and surface tension, and the surrounding environment. It influences how a jet or spray covers a target surface, how quickly fluids mix with surrounding air, and how much material is lost to drift or overspray.

Applications of Düsenwinkel occur in multiple fields. In agriculture, the spray angle affects crop coverage and drift risk; in coating technologies, it determines uniformity of deposited layers; in combustion and propulsion, the jet divergence impacts mixing, combustion efficiency, and thrust characteristics. Measurement and optimization typically rely on visualization and imaging techniques, laser-based diagnostics, or standardized spray tests to characterize the angular distribution and pattern of the jet.

Overall, the Düsenwinkel is a key parameter in nozzle design and application, linking geometry, fluid properties, and performance goals to control how a jet or spray interacts with its surroundings.
