Validation of cooling-tower plume model at the Philippsburg and Geysers sites

; ; ;
New data on visible plumes have become available from Philippsburg (single natural-draft cooling tower, approx. 800 MWe) in West Germany and the Geysers site (single mechanical-draft cooling towers approx. 100 MWe) in northern California, USA, for testing models for cooling tower plume rise. The Philippsburg data were taken under humid conditions in which significant plume thermodynamic effects are expected to occur. The Geysers data were taken under hot and dry ambient conditions (minimizing plume thermodynamics) but with the site in complex terrain. The Philippsburg and Geysers data represent extremes in ambient conditions not generally observed with previous data (Chalk Point, Luenen, and Paradise sites) used for earlier model validation. For Philippsburg, fourteen American models for natural-draft cooling tower plume (NDCT) dispersion have been tested with 16 data cases. All the models tested employ the one-dimensional integral method. The performance of the models at Philippsburg has then been compared with the performance of the same models with 39 field data cases previously assembled form our earlier model validation study. The predictive accuracy of all of the 14 models tested was about the same for the 16 Philippsburg cases as for the earlier 39 cases.
