Summary

EXPERIMENTS WERE PERFORMED TO MEASURE NUSSELT NUMBERS AND PRESSURE LOSS COEFFICIENTS FOR ANNULAR-FINNED TUBES DEPLOYED IN A ONE-ROW ARRAYOR IN AN IN-LINE OR A STAGGERED TWO-ROW ARRAY. FOR THE ONE-ROW ARRAYS, BOTH NUSSELT NUMBERS AND THE PRESSURE LOSS COEFFICIENT WERE HIGHLY SENSITIVE TO THE TRANSVERSE PITCH. NUSSELT NUMBERS FOR THE FIRST ROW OF A TWO-ROW ARRAY DID NOT DEVIATE APPRECIABLY FROM THOSE OF THE CORRESPONDING ONE-ROW ARRAY. FOR THE TUBES OF THE SECOND ROW, NUSSELT NUMBERS FOR THE STAGGERED ARRAYS GENERALLY EXCEEDED THOSE FOR THE IN-LINE ARRAYS AND WERE LESS SENSITIVE TO THE LONGITUDINAL PITCH. THE OVERALL PRESSURE DROPS FOR THE TWO-ROW, STAGGERED ARRAYS WERE ALSO QUITE INSENSITIVE TO THE PITCH.
