Extremely fast jets and vortex dynamics of single laser bubbles
* Präsentierender Autor
Zusammenfassung:An extreme fast jet has recently been predicted by the authors for cavitation bubbles close to a solidboundary. Until then jet velocities were known only in the order of ~100 m/s for large distances from theboundary, whereas the extreme fast jet is supposed to reach orders of ~1000 m/s when the bubblecollapses in the direct vicinity. The lifetime of this jet is in sub- or few microseconds range. Theseproperties make the experimental confirmation a laborous task. However, the authors made effort tophotograph it. The results are discussed and a considerable lower bound for the jet velocityof ~300 m/s can be given.
