    Description / Table of Contents: Zusammenfassung Der Durchfluß auf der Saugseite und an der Endwand eines Kanals zwischen zwei benachbarten Turbinenschaufeln wird sichtbar gemacht und mit gemessenen Massen-(Wärme)strömen der selben Oberflächen verglichen. Neben den hufförmigen Wirbeln und Durchflußwirbeln werden mehrere kleinere Wirbel in der Nähe der Verbindungsstelle von Schaufel und Endwand gebildet und die Ursache ihrer Entstehung wird diskutiert. Die Wirbel lösen sich von der Endwand ab und bewegen sich über die Spannweite der Schaufel. Diese Wirbel, manchmal als gegenläufige rotierende Paare, sind für die wesentlichen lokalen Variationen des Wärmeflusses verantwortlich.
    Notes: Abstract A visualization of the flow on the suction side and end-wall of a passage between two neighboring turbine blades is compared with mass (heat) transfer measurements on the same surfaces. Besides the horseshoe and passage vortices, there are several smaller vortices formed near the junction of blade and end-wall whose origins are discussed. The vortices detach from the end-wall and move up the blade's span. These vortices, sometimes in counter rotating pairs, are responsible for substantial local variations of heat transfer.

    Description / Table of Contents: Zusammenfassung Strömung und ' Wärmeübertragung in einem geschlossenen zylindrischen Hohlraum, der um seine Achse rotiert, werden in dieser Arbeit untersucht. Das Kühlmittel tritt ein und aus durch zentrale Öffnungen in den Abschlußwänden. Mit dieser Anordnung kann man rotierende Hohlräume in Gasturbinen und Luftverdichtern nachahmen. Die Navier-Stokes- und Energiegleichungen werden durch eine Differenzenmethode gelöst, die sich an stationäre und nichtstationäre Bedingungen anpassen läßt. In einigen Fällen wurden auch Auftriebskräfte berücksichtigt, die mit den Fliehkräften verknüpft sind. Alle Lösungen gelten für laminare Strömung. Im untersuchten Bereich unterdrückt die Rotation die Zirkulationsströmung und verringert den Wärmeübergang im Vergleich zum ruhenden System. Auch der Auftrieb reduziert den Wärmeübergang durch den Zerfall der Zirkulationsströmung in den äußeren Teilen des Behälters. Erst ein starker Auftrieb erhöht leicht den Wärmeübergang. Der Kühlstrom war in einem Kanal nahe der Zylinderachse eingeschnürt mit nur geringer Vermischung mit dem übrigen Behälterinhalt.
    Notes: Abstract An analysis is made of the fluid flow and heat transfer processes in a circular cylindrical enclosure rotating about its own axis. A coolant is passed through the enclosure, entering and leaving through centrally located apertures in the end walls. This configuration is intended as a model of rotating enclosures in devices such as gas turbines and air compressors. The Navier-Stokes and energy equations were solved by a finite-difference formulation which can accommodate either steady or transient conditions. Buoyancy forces associated with the rotational body forces were included in some cases. All solutions were performed for laminar flow. For the parameter ranges investigated it was found that rotation inhibited the recirculating motion within the enclosure and thereby decreased the heat transfer relative to that for the stationary enclosure. Buoyancy further reduced the heat transfer owing to the break up of residual circulatory motions in the outer portion of the enclosure. Still stronger buoyancy brought about a slight increase in the heat transfer. The coolant flow was confined to a corridor adjacent to the axis of the enclosure, and there was no mixing between the coolant and the fluid in the enclosure proper.

    Description / Table of Contents: Zusammenfassung Die Forschung auf dem Gebiete Wärmeübertragung wird im Wesentlichen durch Neuentwicklungen in der Technik angeregt. In den letzten 30 Jahren lieferten vor allem der Gasturbinenbau, die Flug- und Raumfahrttechnik und die Reaktortechnik Wärmeübergangsprobleme für die Grundlagenforschung. Diese werden besprochen und noch ungelöste Probleme werden aufgezählt. Neuerdings brachten die thermische Entwertung der Atmosphäre und der Gewässer und die Möglichkeit der kontrollierten Kernfusion neue Aufgaben für die Wärmeforschung.
    Notes: Abstract Heat transfer research is instigated primarily by new developments in technology. In the last thirty years the fields of gas turbines, aeronautics and astronautics and nuclear power contributed many problems for basic heat transfer studies. These are discussed and presently unsolved problems are enumerated. In recent years thermal pollution and the possibility to achieve controlled fusion posed new challenges for heat transfer research.
