Pressure drop and heat transfer correlations for use in CFTL bundle analysis
Description
The friction factor and Stanton number for flow past a roughened surface are determined by the parameters A and R(h+) of the universal law of friction and the parameters Asub(H) and G(h+) of the universal law of heat transfer. The methods used for experimental determination of these parameters for the particular roughness and rod diameter proposed for use in the Core Flow Test Loop (CFTL) are presented and recommended values for use in CFTL bundle flow analysis are prescribed.

Reibungsbeiwert und Stantonzahlen fuer die Stroemung ueber rauhe Oberflaechen sind bestimmt durch die Parameter A und R(h+) des Wandgesetzes fuer die Geschwindigkeitsverteilung und die Parameter Asub(H) und G(h+) des Wandgesetzes fuer die Temperaturverteilung. Die Methoden zur experimentellen Bestimmung dieser Parameter werden dargelegt fuer die spezielle Rauhigkeit und den Stabdurchmesser, die fuer die Untersuchungen in Core Flow Test Loop (CFTL) vorgeschlagen wurden. Empfohlene Werte fuer die Analyse der CFTL-Stabbuendel werden angegeben. (orig.)
