Summary

THE ANALYSIS OF VISUAL PATTERNS OF FLOW DISTRIBUTION IN FINNED TUBE BANKS WITH INDIVIDUAL FINS PERMITS THE SEPARATION OF MAJOR FACTORS AFFECTING HEAT TRANSFER AND PRESSURE DROP. A FLOW MODEL AND GOVERNING DIMENSIONLESS VARIABLES ARE ESTAB-LISHED ON THE BASIS OF THIS ANALYSIS AND SIMILARITY WITH HEAT TRANSFER PHENOMENA IN CHANNELS. HEAT TRANSFER AND FRICTION FACTOR CORRELATIONS ARE RECOMMENDED FOR CROSSFLOW OVER STAG-GERED TUBE BANKS WITH PLAIN AND SEGMENTED FINS IN THE RANGE OF REYNOLDS NUMBERS = 300-10,000. CORRELATION COEFFICIENTS ARE EVALUATED USING ORIGINAL AND PUBLISHED EXPERIMENTAL DATA. THE CORRELATIONS CORRESPOND WITH MOST OF THE AVAILABLE TEST DATA WITHIN 10%.
