- Abstract
- Twelve mathematical models for salt drift deposition from natural draft cooling towers are evaluated in terms of performance with prototype data and validity of theoretical assumptions. Model predictions are compared with field data acquired at the Chalk Point Power Plant during 1975, 1976, and 1977. Large, often several orders of magnitude differences among model predictions existed for runs with the 1975-1977 data. Since the field data are limited, extrapolation of the model's performance to significantly different types of environmental conditions and farther from the tower than 1 km should be done with caution. Each model reviewed was shown to have limitations in two categories. There were assumptions that were either not correct physically or not state-of-the-art. Secondly, there were assumptions whose correctness is presently unknown. Sensitivity and comparative studies were also conducted and are described.
