Summary
Temporal mean and turbulence characteristics of two-dimensional wall jets along convex or concave surfaces of constant radii have been measured in a moderate range of curvature. The wall jets are at an inlet to the curved surfaces in a state developed fully as a plane wall jet, where the mean velocity profile becomes similar. Deviations of turbulence energy balances across the wall jets due to the curvature are discussed in comparison with those of a free jet and of a plane wall jet.
Übersicht
Zeitliche Mittelwerte und turbulente Eigenschaften zweidimensionaler Wandstrahlen an konkaven oder konvexen Wänden mit mäßiger, konstanter Längskrümmung sind gemessen worden. Beim Einströmen in den gekrümmten Teil der Wand sind die Wandstrahlen im Zustand eines voll ausgebildeten, ebenen Wandstrahls mit ähnlichen Geschwindigkeitsprofilen. Einflüsse der Krümmung auf die Turbulenzenergie-Bilanz werden im Vergleich zu Freistrahlen und ebenen Wandstrahlen diskutiert.
