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 established 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 staggered tube banks with plain and segmented fins in the range of Reynolds numbers Re{sub h} = 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%.
