Summary
An experimental method for studying the high speed impact of a liquid drop on a liquid surface is described in which the liquid surface is moved against the stationary drop. Photographs are presented of the impact of a water surface at 47,7 m/sec on a stationary water drop 0,175 cm diameter. Proposals are made for further work to resolve certain discrepancies between results obtained using this method and those derived from earlier work in which drops fall freely onto a standing surface.
Übersicht
Es wird eine experimentelle Methode zur Untersuchung des Aufprallens von Flüssigkeitstropfen auf eine Flüssigkeitsoberfläche beschrieben, bei der die flüssige Fläche mit hoher Geschwindigkeit gegen einen stationären Tropfen bewegt wird. Fotos des Aufprallvorgangs bei Geschwindigkeiten von 47,7 m/s mit Tropfen von 0,175 cm Durchmesser werden gezeigt. Weiterhin werden Vorschläge gemacht, wie bei künftigen Untersuchungen ] gewisse Unterschiede in den Ergebnissen nach der hier beschriebenen Methode und bei frei fallenden Tropfen aufgeklärt werden könnten.
