The report discusses the test program and performance analysis of a single-cell mechanical-draft wet/dry cooling tower in Cliffside, NC. Objectives of the program were to obtain performance data and results on mass transfer, heat transfer, fluid flow, plume formation, and acoustic characteristics for comparison with models/theories. Correlations are presented for the wet-fill mass transfer coefficient, wet-fill water loss, Colburn j-factor for the finned tubes, and fan efficiency in terms of one or more of the following: water loading in the tubes, air loading over the fins, log mean humidity difference, outlet water temperature, Reynolds number, and air-flow rate. Acoustic data were fitted to a series of curves for each of the eight octave bands. Attempts to model plume data failed. The report also describes the test facility, test procedures, instrumentation, data acquisition, and data reduction.
