Abstract

Bekannte Düsen erzeugen Fluidstrahlen, deren Geschwindigkeit in der Strahlachse maximal und in der Peripherie minimal ist. Durch Reibungsverluste reduziert sich die periphere Geschwindigkeit über die Strahllänge, so dass die Kohärenz verloren geht und beispielsweise ein Flüssigkeitsstrahl zu Tropfen beginnt. Wird dagegen eine Strömung (S1) über eine Zuführstrecke (1) mit Beruhigungs- und Homogenisierungsgliedern (3)geführt, so kann sie über eine Kantendüse (9) laminarisiert werden. Der erzeugte Strahl (S2) besitzt ein Geschwindigkeitsprofil, welches gegenüber demjenigen aus bekannten Düsen verschieden ist, d.h. die höchste Geschwindigkeit ist in der Peripherie zu verzeichnen. Damit lassen sich zahlreiche physikalische Messverfahren und Prozesse verbessern und auch dekorative optische Wirkungen erzielen. Der Erfindungsgegenstand ist auch bei der Feuerbekämpfung und für den Polizeieinsatz geeignet.

Figure 00000001
Known nozzles generate fluid jets, the speed of which is maximum in the jet axis and minimal in the periphery. Frictional losses reduce the peripheral speed over the jet length, so that the coherence is lost and, for example, a liquid jet begins to drip. If, on the other hand, a flow (S1) is guided over a feed section (1) with calming and homogenizing elements (3), it can be laminated via an edge nozzle (9). The generated jet (S2) has a speed profile which differs from that from known nozzles, ie the highest speed is recorded in the periphery. This allows numerous physical measurement methods and processes to be improved and decorative optical effects to be achieved. The subject of the invention is also suitable for fire fighting and for police use.
