Spray energy release (SER) approach to analyzing spray system performance

Spray-cooling systems for thermal power plants are more controllable, cheaper to construct and operate, and equal in thermal performance when compared with other cooling systems. In order to achieve a reliable method for predicting the performance of an open atmosphere spray cooling system, a mathematical model is developed using the energy release of the spray (SER), knowledge of the spray distribution, and a spray mixing parameter. Empirical data for a single spray is obtained and used to predict the performance of the whole spray field. Both a small and a large spray system were used to check the validity of the model. Good agreement was found in both cases. (LCL)
