A generalized heat transfer correlation for louver fin geometry

A generalized heat transfer correlation for louver fin geometry is developed with the aid of a large data bank. This data bank consists of 91 samples of louvered fin heat exchangers with different geometrical parameters, including louver angle, tube width, louver length, louver pitch, fin length and fin pitch. For the corrugated louver fin geometry, it is shown that 89.3% of the corrugated louver fin data are correlated within +/-15% with mean deviation of 7.55%. The inclusion of the plate-and-tube louver fin data in the heat transfer correlation (equation (Al)) results in a mean deviation of 8.21%. Copyright (C) 1996 Elsevier Science Ltd.
