摘要：

A flow visualization study of the louvered fin geometry commonly used in automotive heat exchangers was performed using a dye injection technique with 10:1 scale models. The geometrical parameters, louver pitch, louver angle, and fin pitch were varied to determine their effect on the flow structure. Tests covered Reynolds numbers of 400-4000 based on louver pitch. Data are presented in the form of a dimensionless flow efficiency (defined in terms of the mean flow angle relative to the louver angle) and Reynolds number. Correlations are developed to predict the flow efficiency as a function of dimensionless geometrical groups and Reynolds number. The flow structure is also discussed.
