THE EXPERIMENTAL DETERMINATION OF AERODYNAMIC TOTAL-PRESSURE LOSSES FOR HEAT-EXCHANGER SURFACES CONSIDERED FOR THE 7- BY 10-FOOT TRANSONIC WIND TUNNEL,

Abstract

Tests were performed to determine the aerodynamic total-pressure losses of several configurations of finned and bare tubing arranged as heat exchanger surfaces. The results indicate that a pressure coefficient (delta p/q) of 8.3 was obtained for the optimum finned tube arrangement which consisted of a six-row configuration containing 1.0-inch diameter tubing in 3.5-inch triangular pitch; the thin segmented and helically wrapped copper fins bonded to the tubing were spaced 10 per inch.
