Description:
The report describes work to (1) determine experimentally the performance and operating characteristics of a plate-fin heat exchanger during dry/wet or 'deluge' operation and (2) continue developing the deluge heat/mass transfer model. This work supports the improvement of power plant cooling systems that conserve fresh water in an environmentally and economically viable manner. The experiments identified important trade-offs concerning deluge cooling; these are discussed. The earlier deluge model was refined and extended to the simultaneous calculation of heat transfer and evaporation from wetted surfaces. Experiments showed the model to be an excellent predictor of heat exchanger performance during deluge operation.
