Determination of Heat-Transfer Coefficients and Pressure tosses and their Correlation for Design of a Air-Cooled Condenser
초록
These experiments is to determine design equations for heat transfer and for pressure drop in a new designed heat exchanger with the waved circular fin tube bundles under various experimental conditions. The results with waved circular fin tube bundles are compared with those with the flat circular fin tube bundles. Heat transfer coefficients in the waved circular fin tubes were enhanced to about 50% in comparison with those in the flat circular fin tubes, This is expected to reduce the capacity of a heat exchanger up to 30%.
