Type of article: Article

Summary

A SCALED-UP MODELLING TECHNIQUE WAS EMPLOYED TO INVESTIGATE THE EFFECT OF THE GEOMETRICAL CHARACTERISTICS OF INTERRUPTED SURFACES ON HEAT TRANSFER AND PRESSURE DROP IN COMPACT HEAT EXCHANGERS EQUIPPED WITH OFFSET STRIP AND SLOTTED FINS. THE TEST CORES, EACH CONSISTING OF A NUMBER OF MACHINED COPPER FINS, WERE TESTED IN A SUBSONIC WIND TUNNEL WHILE MEASUREMENTS WERE MADE OF THE HEAT TRANSFER AND PRESSURE DROP. THESE DATA ARE PRESENTED IN TERMS OF THE COLBURN J-FACTORS AND FANNING FRICTION FACTORS PLOTTED AGAINST THE REYNOLDS NUMBER. THE ARTICLE GIVES EMPIRICAL CORRELATIONS FOR THE HEAT TRANSFER AND PRESSURE DROP CHARACTERISTICS OF OFFSET STRIP FINS.
