Konvektive Wärme/Stoff‐Übertragung und Druckverlust in Rohrbündeln bestehend aus tropfenförmigen Rohren

The effect of introducing tip clearance to a liquid cooled array of shrouded pins fins is examined. Three arrays of height to diameter ratio ranging from 0.5 to 1.1 were evaluated experimentally. The arrays were exposed to a uniform heat flux of 0.02 to 0.26 W/mm2 and cooled with water through a nominal Reynolds number range of 200 to 10,000. Tip clearance of 0 to 25% of pin height was assessed. Mean heat transfer rates and adiabatic pressure drop across the array were determined and empirical correlations are proposed. The introduction of clearance was seen to increase overall heat transfer in some cases.
