Description

Verfahren zur Verminderung der Strömungswiderstände in Leitungen Bei der Fortleitung von flüssigen oder gasförmigen Körpern oder Gemischen derselben durch Leitungen treten Strömungswiderstände auf, die Druckverluste, Geschwindigkeitsverluste, Energieverluste zur Folge haben. Besonders groß sind diese Verluste bei Querschnittsänderungen der Leitung, so daß z. B. die durch allmähliche QuerschnittsvergröBerung der Leitung bewirkte Umsetzung der in einem Flüssigkeits- oder Gasstrom enthaltenen kinetischen Energie in potentielle nur unvollständig erfolgt. Eine Verminderung dieser Verluste Mt sich nach der vorliegenden Erfindung dadurch erreichen, daß der Wandung der mixt konstantem oder veränderlichem Querschnitt ausgeführten Leitung oder Teilen derselben eine oszillierende Bewegung erteilt wird, deren Richtung eine Komponente enthält, die abweicht von der im Strömungssinn genommenen Richtung der gedachten Achse der Leitung.Method for reducing the flow resistance in lines Bei the forwarding of liquid or gaseous bodies or mixtures thereof flow resistances occur through pipes, the pressure losses, speed losses, Result in energy losses. These losses are particularly great when the cross-section changes the line, so that z. B. the gradual increase in cross-section of the line effected conversion of the kinetic contained in a liquid or gas stream Energy in potential is only incomplete. A reduction in these losses Mt can be achieved according to the present invention in that the wall mixes constant or variable cross-section or parts thereof an oscillating movement is given, the direction of which contains a component, which deviates from the direction of the imaginary axis taken in the direction of flow Management.

Als einfachstes Beispiel sei ein kreiszylindrisches Rohrstück angeführt, das innen von Luft durchflossen ist und das um seine Längsachse in oszillierende Bewegung versetzt wird. Durch diese oszillierende Bewegung wird nun der Widerstand, den die Luft beim Durchströmen des Rohrstückes erfährt, vermindert.The simplest example is a circular cylindrical pipe section, which has air flowing through it inside and which oscillates around its longitudinal axis Movement is displaced. Through this oscillating movement, the resistance is now which the air experiences when flowing through the pipe section is reduced.

Statt des im angeführten Beispiel gewählten zylindrischen Rohrstückes kann auch eine Leitung mit in Richtung der Strömung zu- oder abnehmendem Querschnitt (z. B. Turbinensaugrohr, Diffusor, Düse) in der oben beschriebenem Weise bewegt werden.Instead of the cylindrical pipe section selected in the example given can also be a line with an increasing or decreasing cross-section in the direction of the flow (z. B. turbine suction pipe, diffuser, nozzle) moved in the manner described above will.
