Breakdown of Pulsating Water Jets

zweidimensionales bewegtes Bild

Interaction of running-time effects and surface tension (Rayleigh instability) in a fluid beam with velocity modulation. Basic velocities: 4 m/s and 2 m/s; jet diameter: 3.2 mm or 5 mm; disturbance amplitudes: 0 to 5 %. Pressure chamber with pulsator, pressure probe, and anemometer. Decay in drops. Slow motion photography (20-200 Hz) with synchronous stroboscopic illumination. Overlap effects. In a horizontal beam: bead chains and umbrellas. In a vertical beam: crowns, bottles, and bubbles.
