Swirling hollow water jets under the influence of inertia and surface forces
Abstract
Theoretical and experimental investigations of swirling hollow water jets under the influence of gravity are presented. The flow is assumed to be frictionless, and the axially symmetrical contour of the water jets is determined as a function of the pressure forces and the surface tension. The influence of gravity and of the geometry of the jet-forming nozzle on the contour of the hollow jet is discussed in detail. The Froude, Weber, and Euler numbers are used as the characteristic parameters of the flow. The validity of the calculation method is demonstrated by the good agreement it achieves with the experimental results.
