- W2031170035 abstract "Natural convection in an inclined annular space heated and cooled on the end plates and thermally insulated on the concentric cylinder walls was studied experimentally and theoretically. As the heated surface was inclined from the lower horizontal position to an upper horizontal position, the mean Nusselt number at first decreased, then increased and finally decreased to unity as the mode of circulation switched from a symmetrical array of roll cells to distorted and oblique roll cells to a single circulation. The flow pattern is portrayed with streaklines computed numerically using a three-dimensional model and also with photographs. On étudie expérimentalement et théoriquement la convection naturelle dans un espace annulaire chauffe et refroidi à ses extrémités planes et isole thermiquement aux parois latérales concentriques. Lorsque la surface chaude est inclinée depuis la position horizontale inférieure jusqu'à la position horizontale supérieure, le nombre de Nusselt moyen décroit tout d'abord, puis croît et décroît finalement jusqu'à l'unité, tandis que le mode de mouvement passe d'un arrangement symétrique de rouleaux cellulaires à des rouleaux distordus et obliques et à une circulation unique. La configuration d'écoulement est décrite à partir d'un traitement numérique appliqué à un modèle tridimensionnel et aussi par des photographies. In einem geneigten Ringspalt, der an den Endflächen geheizt und gekühlt wurde und an den konzentrischen Zylinderwänden thermisch isoliert war, wurde die freie Konvektion experimentell und theoretisch untersucht. Wenn die geheizte Endfläche von der unteren waagerechten Position in die obere waagerechte Position geschwenkt wird, verringert sich zunächst die mittlere Nusselt-Zahl, dann erhöht sie sich und geht schlieβlich auf eins zurück, analog zur Art der Zirkulation, die von einer symmetrischen Rollzellenanordnung über verzerrte und schiefe Rollzellen zu einer Einzelzirkulation übergeght. Das Strömungsbild wird durch numerische Berechnung der Streichlinien nach einem dreidimensionalen Modell und ebenfalls mit Hilfe von Fotografien dargestellt.
