RÉSUMÉ
This article experimentally investigates the heat transfer and friction characteristics of slit-finned heat exchangers. The present fins have radial slits. Investigation has focused on the effect of fin pitch and slit geometry (slit height, slit width, etc.). Results show that the heat transfer coefficient increases as the fin pitch increases. The friction factor, however, decreases as the fin pitch increases. Possible reasons for this involve the slit pattern between neighboring fins. The slit height does not seem to have a significant effect on either the heat transfer coefficient or the friction factor as long as the slits protrude outside of the approaching boundary layer. The S4 fin, which has the longest and highest slits, yielded the largest heat transfer coefficient. Possible reasons for this involve the slit arrangements. A new correlation predicts 92.9% of the heat transfer coefficients and 100% of the friction factors within ±10%.
