Bestimmung des Wärmeübergangs von Kugelschüttungen an durchströmendes Gas mit Hilfe der Stoffübergangs‐Analogie

Abstract: Arbeitsgemeinschaft BBC-Krupp, Dusseldorf, Mannheim und Julich Mit Hilfe der Analogie Stoffubergang -Warmesbergang wurde der Warrneubergang von Kugelschuttungen a n durchstromendes Gas bestirnmt. Zu diesem Zweck wurden Naphthalin-Kugeln in einen Kugelhaufen eingelegt und der Gewichtsverlust nach Durchstromen von Luft gemessen. Hieraus k a n n der Warmeubergang errechnet und seine Nu' = f' (Re, Sc) Gases zu messen4), oder aus dem zeitlichen Verhalten des Erhitzens bzw. Abkuhlens des Kugelhaufens im Gasstrom a… Show more

“…In our experiments the method of sublimation of naphthalene in air was used (see also [4,5]). The naphthalene particles were spherical, diameter ratios of D/d= 1.41, 1.98 and 3.77 were realized, the bed length, the test temperature, and the Reynolds number were varied (2.4<Reo<1500).…”

“…All runs were made a t room temperature. An idealized flow pattern around spheres in simple cubic packing is presented.Although extensive work has been done on various overall transport phenomena, such as the overall mass and heat transport from randomly packed beds to flowing fluids (1, 6, 9, 10, 12, 16,18,20) and from single particles such as single spheres (8, 10) or cylinders to flowing fluids, only limited references to previous investigations of the local transport phenomena from spheres in packed beds to flowing fluids are known. It was the objective of this work to investigate the local rates of mass transfer from slightly soluble spheres in a packed bed to a flowing fluid.…”
