    Description / Table of Contents: Zusammenfassung Der Druckverlauf und der Stoffübergang entlang einzelner Profilrohre mit Oval-, Lanzetten- und Rautenquerschnitt wurde experimentell untersucht. Der Stoffübergang wurde dabei durch Messung der Diffusionsrate von Naphthalin an Rohren aus Naphthalin ermittelt. Des weiteren wurden der lokale und mittlere Stoffübergang sowie der Druckverlust in versetzt angeordneten zehnreihigen Profil-Rohrbündeln untersucht. Die Versuchsergebnisse werden mit Hilfe halb-empirischer Beziehungen für den Impuls-und Stofftransport beschrieben.
    Notes: Abstract The pressure distribution and the mass transfer rate along single profile tubes with lanceolate, oval- and diamond-shaped cross-section have been experimentally investigated. The mass transfer rate has been determined by measuring the diffusion rate of naphthalin in air on special tubes made of naphthalin. Furthermore, the local and mean mass transfer rate as well as the pressure drop characteristics of arrays with 10 rows have been determined. The experimental results are described with the aid of semi-empirical relations for the momentum and mass transport.
