SYSTEMATIC INVESTIGATIONS ON THE HEAT TRANSFER AND FLOW RESISTANCE OF FINNED TUBES, A CONTRIBUTION TO THE APPLICATION OF SPECIAL TUBES IN GAS COOLED REACTORS (in German)
In spite of the importance of fin tube banks in heattransfer equipment for atomic power reactors, few experimental data previously have been available on convection heat transfer and pressure drop to flow of gases sweeping the fin tubes in cross-flow. New experimental observations on this subject therefore are of the utmost importance. The present investigations refer to measurements of heat transfer and pressure drop of single brass fin tubes for cross flow. The influence of fin height, fin spacing and Reynolds number on both qualities or tubes is graphically plotted. With certain restrictions the results on single brass tubes can be transferred to the technically more interesting banks of steel tubes, because all measurements on fin tubes are plotted according to the relationship of their qualities to the plain tube. Thus a statement about the economy of fin tubes and about the optimal dimensions is made possible. The volume as well as the pressure drop of fin tube heat exchangers, plotted against fin height with constant total heat input, pass a minimum at fin heights between 5 and 10 mm. (auth)
