Zusammenfassung

In einem Wasserkanal wurden Versuche über den laminar-turbulenten Umschlag einer zweidimensionalen Strömung durchgeführt. Geschwindigkeitsmessungen der vorderen und hinteren Randzonen von künstlich erzeugten Turbulenz-Kernen ergaben eine (auf die mittlere Strömungsgeschwindigkeit und die Kanaltiefe bezogene) kritische Reynolds-Zahl von 1025±25. Messungen der Intermittenz längs des Kanals bei den Reynolds-Zahlen 3460, 3570 und 3850 zeigten, dass die Umschlagstheorie nach Emmons auch für Kanalströmung sinnvoll ist.
