Zusammenfassung
Das Auftreten kinematischer Wellen ist an das Bestehen eines funktionellen Zusammenhanges zwischen den Feldgrößen gebunden. Ein interessantes Anwendungsgebiet ihrer Theorie stellen Strömungsvorgänge dar, bei denen sich diese Relation dadurch ergibt, daß die Einflüsse von Reibungskräften und Schwerekräften dominieren, während Trägheitseffekte global nur von untergeordneter Bedeutung sind. Als typische Beispiele dafür werden turbulente und laminare Filmströmungen, Ausbreitungsvorgänge im Geschiebe von Flüssen sowie Sedimentationsvorgänge in Zweiphasenströmungen behandelt.
Summary
The occurrence of kinematic waves is characterized by the existence of a functional relationship between the dependent flow-variables. Interesting flow problems which can be handled by their theory are phenomena where this relation expresses the fact that frictional forces and gravity forces dominate while inertia effects are neglegible. As typical examples turbulent and laminar flows of thin sheets of fluid, wave propagation phenomena in erodible beds and sedimentation processes in two-phase-flows are considered.
